About the Game
You are a slugcat. The world around you is full of danger, and you must face it – alone. Separated from your family in a devastating flood, you will need to find food and shelter between terrifying torrential downpours which threaten to drown all life. Climb through the ruins of an ancient civilization, evade the jaws of vicious predators, and discover new lands teeming with strange creatures and buried mysteries. Find your family before something makes a meal of you!
Inspired by the simplicity and aesthetics of 16-bit classics, this survival platformer requires clever decision-making, both to catch your own prey and to avoid the jaws of hungry predators. Each ravenous foe in your path will be cunning, vicious and always on the hunt – eager to sink their teeth into you, or even each other. As a small, soft slugcat you must rely on stealth and wit rather than force: learn the ecosystem and turn their strengths to your advantage. Maybe then you can survive… Rain World!

We have a new set of patch notes hot and ready.
This patch adds Watcher to safari mode, improves ripple spawn pathing, and more… so much more… The patch notes are two pages long.

Fixed inconsistencies in the warp map where bad warps could sometimes show up on the map even though they're unusable.
Fixed warp point markers not showing up when viewing region maps inside of the hibernation screen and title screen Region menu.
Fixed some situations where the region map ends up scrolled to random or undiscovered locations on the map when the map is first opened for viewing.
Fixed "Vulnerable Jellyfish" Remix config not actually making jellyfish vulnerable to spear throws.
Fixed "Breath Time Leniency" Remix config only giving leniency to Rivulet and not to any other slugcats.
Fixed a select few creatures that would crash the game if adult Sand Grubs attempted to grab them.

Made it so you can still return to the hibernation screen after seeing a Watcher dream sequence.
Added protection against flame jets when sitting inside of pipe entrances or traveling through a pipe.
Made Weaver Threads display every time a sealed warp is visited on a cycle, not just on the first time it is visited.
Improved the swimming and pipe traversal behavior for Frogs and Rats.
Made it so multiple frogs can attach at the same time to larger creatures.
Improved the path following for Sky Whales.
Improved the collision handling and interaction between creatures and sloped terrain.

This might be the longest patch notes I have ever received. It takes up almost two pages in the Google Doc I am reading from. If you would like to read the full patch notes, you can read them below!
Patch Notes
Fixed a large number of memory leak issues that could lead to the game crashing randomly over an extended play session (especially on the Nintendo Switch version).
Made a large number of miscellaneous performance optimizations that should improve frame rates with some creatures or in certain areas of the game.
Fixed color palettes rendering incorrectly inside ripple rifts and within the Migration Path region on the Nintendo Switch version of the game.
Fixed flashing graphical artifacts that could randomly occur on the Nintendo Switch version of the game in the presence of Sentient Rot floater particles.
Fixed graphics sometimes glitching out for a single frame, or sand terrain colors glitching for a single frame, when switching between rooms or screens on the Nintendo Switch version of the game.
Fixed some graphics and particle effects unintentionally rendering with solid square borders on PlayStation and Nintendo Switch versions of the game.
Warp points now pull important key items from a larger radius so there's less chance of them accidentally getting left behind.
Relocated a couple player-generated warp target destinations so they won't ever spawn above bottomless bodies of water that can swallow player's important items after traveling through the warp.
Fixed pearls not getting brought through the portal into Ancient Urban sometimes.
Fixed the map icon still showing a region as being rotted even after all rooms in that region have had their rot purified.
Fixed rot lizards still remaining as rotted on subsequent cycles even after the rot has been purified from the room they spawned in.
Fixed the Prince not giving the player the mark during Watcher's final ending sequence if the game was set to certain languages.
Fixed additional issues with key item trackers that could cause the game to crash if loading into a room adjacent to another room with a tracked key item.
Fixed rooms containing void spawns crashing the game in Jolly Co-op mode if Player 1 got killed in a way that despawns their corpse.
Fixed the "Friends Sheltered" counter on the statistics screen always incrementing every cycle when Jolly Co-op is enabled, even if a friend wasn't sheltered that cycle.
Fixed an occasional crash with Drill Crabs due to their data in the save file being saved incorrectly.
Fixed one of the Watcher tutorial messages not having been translated outside of English.
Fixed adult and baby sandgrub spawning working improperly in Sandbox mode, where the number of adults/babies placed didn't match the amount of adults/babies that actually spawned.

Fixed certain Downpour tutorials never displaying if you had previously been shown the starvation tutorial during other slugcat campaigns.
Excluded certain minor creatures like batflies, leeches, and coalescipedes from spawner tracking, which could cause the no creature spawning glitch to still occur in certain scenarios.
Another fix for whales in the Fractured Gateways region in which they could still spawn in invalid locations sometimes.
General fix for offscreen creatures like Miros Birds, etc, where they also could sometimes spawn in rooms or locations they're not meant to.

Hey slugcats,
New Patch Alert!
This patch fixes regions in the Watcher campaign sometimes failing to spawn any creatures, fixed tracked key items sometimes respawning in previous shelter, and more.
If you would like to read full patch notes you can read them below!
Patch Notes
Fixed regions in the Watcher campaign sometimes failing to spawn any creatures depending on how the warp points were interacted with.
Fixed tracked key items sometimes respawning in the previous shelter that they were stored in, rather than the most recent shelter location.
Fixed the screen sometimes shaking violently or the screen going black in certain scenarios where lizards interacted badly with sloped terrain.
Fixed the Passages perk in Expedition mode freezing the game.
Fixed some information in Expedition mode's menus failing to display on certain consoles.
Fixed the Jukebox menu in Expedition mode freezing depending on your music settings.
Fixed a warp point issue with Watcher's final ending that would cause the ending to break if you replayed the ending a second time shortly after the first time playing through that ending. (For players who already are experiencing the glitch in their current save file, this won't retroactively fix it, but hibernating for at least 5 cycles before replaying the ending will also fix that issue in your current save)
Fixed an additional console-exclusive hardlock that would occur after spawning ripple rifts at higher ripple levels and hibernating in the same region as the rift(s). Or equivalently, warp points crashing if warping into a region that includes those player-spawned ripple rifts.
Fixed visual glitches that would occur when entering the void sea while in ripple space.
Fixed the void sea sequences in non-Watcher campaigns breaking in various ways if you were in Jolly Co-op mode and one or more of the characters were playing as The Watcher.
Fixed a bug that caused the wrong illustration to show on Watcher's statistics screen depending on which installed DLCs were enabled/disabled.
Improved the lighting interactions with sloped terrain.
Fixed some memory leaks in the Remix menu.
Fixed a glitched piece of level geometry in the Sinkhole arena that would instantly kill the player.
Fixed an incompatibility with the Region Kit mod that would cause the Heat Ducts region to crash the game for players using that mod.
Updated the speedrun validation strings to include info for cheat configs for Watcher and Remix.
Thanks for reporting these issues to us. If you run into any bugs please report them here!
