About the Game


The Kaisers Fleet approaches! It falls to you to learn the secret language of Morse Code and repel the naval onslaught through timing, tactics and telegraphy.
MORSE is a wave based strategy game elegantly operated with just two controls, Morse and Artillery:
Enter dots and dashes to navigate an ever changing grid of letters and numbers.
Unleash an arsenal of artillery to reveal hidden enemy positions with the flash of your strike and swiftly sink them with precision and speed.
Between waves, upgrade your reconnaissance and firepower and bolster your blockade of sea mines crucial to holding the line. With each wave the waters change, new letters are learnt, shells are spent, ships scuttled and defences tested. Can you prevail?
Telecommunicate. Illuminate. Eliminate. Upgrade. Blockade. Prevail.
Navigate ever changing grid of letters and numbers using the lost language of Morse Code. Learn a handful of simple letters then master the telegraphy tree to fully scale the battlefield. Master different telegraph control schemes such as Iambic and Sideswiper.
German ships are shrouded by the cover of darkness, illuminate their positions using the flash of your artillery strikes. Distant vessels will briefly brighten, land a blast close enough and warships will be permanently revealed.
Rain down salvos of shells on the Kaiser's fleet with your artillery. Deliver direct hits for maximum damage and to save ammunition, consistent precision is rewarded with a faster feed of shells that can breach the hulls of even the strongest ships.
After successfully repelling each assault, pick between a pair of upgrade cards to bolster your arsenal, chosen with either a dot or a dash. Unlock new deadly types of artillery shell, improve your sea mines or enhance your reconnaissance. Upgrades stack so choose wisely!
Deploy a blockade of sea mines to reveal and destroy any ships that slip past your artillery. Mines can be bunched and scattered in various formations. Upgraded mines can withstand damage, have timed detonators and can relay warnings of breaches.
With each wave, a new isogram is chosen, the vertical row extends, the number of units increase and new powerful German vessels emerge from the dark waters. Survive until dawn.
Can you change the world with the push of a button?

BUILD YOUR OWN TELEGRAPH!

Whilst an enjoyable experience with mouse, keyboard or Steamdeck, the authentic way of playing MORSE is with a telegraph key. Here are some of the different types of "homebrew" hardware that players have fashioned to play the game with. Visit the Steam Discussions for the project to learn about how to build your own, including the newly announced Teaspoon Telegraph.

ADDITIONAL FEATURES:

A frantic campaign mode featuring a midnight breach of the Blockade of Germany.
A skirmish mode to hone your telegraphy skills on a breadth of different words.
40 different characters to learn in Morse Code.
3 different telegraph types and calibration settings to tune to your needs.
Put your knowledge and skill to the test with Expert Mode.
Mix up gameplay with a growing collection of modifiers.
Connect up a homebrew or commercial telegraph key for the authentic MORSE experience.

Hey Folks,
\[UPDATE 29/04/2026: After posting the update, I noticed a save bug due to a conflict with the updated demo logic that wiped player progress in the release build, I fixed the bug in question, just make sure when you're updating, DO NOT DOWNLOAD THE UPDATE (23016634), go straight to 23018551. Thanks for your patience.]
As promised, here's the updated build! I've added a couple of small but meaningful changes to MORSE:
+ Iambic Fixed: There was a subtle but fiddly timing issue with the Iambic key that has persisted since launch that I've finally managed to solve! Means that Iambic feels much more fluid and reliable. Thank you for your patience in awaiting this fix.
[img src="https://clan.fastly.steamstatic.com/images//42341374/a0f6d0219cd96099e0af87e375de0a4c9fb4074c.gif"]+ Update revisions: The UI update in the last build I had some complaints about one of the notifications displays obscuring the grid, so I've made that integrate more subtly in the game, popping up only when necessary rather than constantly on screen.
+ Tutorial Disabled for Exercises: Under modifiers, there's the option to disable tutorials, in the last update that didn't turn them off for the learning exercises. That way, you can quickly tweak your telegraph or practice without having to see the whole tutorial on each page.
+ Cursor Toggle: In a previous update I added a cursor for players who were using mouse, but when using keyboard you would see the cursor sitting on the screen. When you press keys, the cursor disappears, when you press either mouse button, the cursor appears.
That's all for now, stay tuned for the demo update dropping in the next few hours!

Hey folks,
Just a very quick update on the MORSE training update: The white transmission frame in the bottom left has been narrowed slightly to take up less space than before.
[img src="{STEAM_CLAN_IMAGE}/42341374/618682888e580073b0325ab3d761b9661c233d09.png"]
Further, I'm going to look into improving the listening mode to be a higher challenge, which I'll get to next week (making it harder to not just lean on mimicking, read my idea for a prototype in this discussion).
Thanks to Cyan for the suggestions, if anyone has any more feedback, bugs or suggestions feel free to reach out! Hope training is going well so far.

Also just wanted to acknowledge the lovely messages from folks about the update and that MORSE is on the cusp of crossing 100 reviews! Very grateful for all your support.

Hey Folks,
Just a quick update after posting the build yesterday:
[img src="{STEAM_CLAN_IMAGE}/42341374/161456af2ce83b7779ec873923c4c947fec7f61f.gif"]
Fixed the display of an achievement which had the wrong totals associated with it.
Whilst fixing the last mentioned bug, based on Seaman Sneed's suggestion, I've added a "ongoing stats" display now so rather than just getting 15/15 after completing an achievement, you'll get the ongoing figure after a second or so delay. This is particularly exciting for "Perfectionist", which now will record your accuracy all the way up to 100%, I am very curious to see if anyone is capable of achieving that!
Fixed a bug which turned off the printout text (got the bool the wrong way around for the minimalist mode).
That's all for now, got some exciting features to work on over the next month, stay tuned for more and let me know if you have any other requests or suggestions!!

Hey folks,
Just thought I'd sneak in just one more small update in 2025 that's fitting for the end of the imminent end of year festivities:
[img src="{STEAM_CLAN_IMAGE}/42341374/4d34e523a2f75ff143b731cc9bebb6956978ecfc.gif"]
EXPLOSIONS!
I commissioned my good friend and talented pixel artist Sinclair Strange to do a bunch of VFX for the project, overhauling the explosions in MORSE. Instead of featuring just a static circle (and basic water animation), explosions now have a bunch of animated variations, splash variants have been added (with more to come) and smoke clouds emerge from the blast. The smoke and water plumes also have variance of frame rate, which creates a bit more dynamism.
I'm very happy with how they've turned out, the new VFX brings more spectacle to combat with explosions visually packing more punch. It's even more cathartic blowing up cruisers.
[img src="{STEAM_CLAN_IMAGE}/42341374/b98160e7060f1f081e306e878dbb12c01118a4a3.gif"]
Bug-wise, I fixed an issue of duplicated letters on one axis (K) on one of the later levels, (thanks to those who helped me track it down) and I've added some more entries to the manual, looking forward to populating this further next year.
Just wanted to give one more signoff before the New Year to thank everyone who's supported MORSE so far, I'm hyped for what 2026 will bring for myself and the project and I'm eager to share some of the new features coming down the pipe!
Happy New Year to all, stay tuned for more soon.

Just a small but important patch for two things:
+ Fixed the issue that a number of people had on the last update where the row wouldn't load in.
+ Cloud Saving: Took me a while to troubleshoot it, but Cloud Saving should now be working on both PC and Steamdeck, thank you for your patience in me sorting it out, please let me know if you encounter any issues.
That's all for now, larger announcement coming soon!
+ Expert and skirmish unlock fixed: There was a fringe bug that if you closed the game after unlocking the modes before the game saved and closed. All sorted.
+ Ability to turn off Morse references: In the previous build, the Morse translations for the letters/numbers were only turned off in expert mode. These can now be fully disabled using H on PC or Y on Steamdeck.
+ Collapsible version of helpsheet: Previously, MORSE had no helpsheet in expert mode, which meant on later levels if submarines rows out of view it was hard to tell. Now, the helpsheet isn't gone, it just collapses smalls and displays the characters on either axis. You can also hold H to fully close the helpsheet if you want.
+ Minor text correction "Plant 3 mines to start the wave", adjusted to 2.
That's all for now, let me know if you find any more bugs and enjoy!
+ Mouse input was disabled for the platform selection page, that has been re-enabled. I really appreciate folks in the Steam discussions highlighting this issue to me quickly.
+ I've added some supporting text on the platform selection screen explaining what controls to push to control the game at that point.
+ Fixed the telegraph beep not stopping on the end screen.
If you find any bugs with the game, please report them here: https://docs.google.com/forms/d/e/1FAIpQLSesjiALOtTlNzpSfrCTejvl8RdSVIL1PgmLisIqtI5Jlvw5KQ/viewform
