Hi, Rebels! 🫡
We have a new small patch for Endless Coffee mode, with some fixes and improvements.
This is probably one of the latest updates of the game for now. But we will be making a cool announcement very soon, so stay tuned to Astro Prospector news!
Full Changelog:
Feature: Capped values in weapons now show a visual indicator, so it is easier to know when a weapon has reached maximum value on that stat.
General: The special day (for those of you who know) has been reworked, fairer distribution of difficulty and it is possible to clear it if you try hard enough. Now Parry does not work there. Text on that day is also translated to more languages.
General: Beach Ball now is visually under everything when size is too big.
Balance: Enemies are a little weaker from Day 15.
Balance: Subtly more Coffee time in Endless Mode.
Fix: It is now impossible to overflow damage and start healing enemies (yes, you could do that). Max damage is capped.
Fix: Show correct max Critical Chance with capped value. (90%)
Fix: Bombs no longer chain react to (almost) infinity, improving performance.
Fix: Better performance in late Endless runs. Deactivating 'Show Damage Numbers' improves further the performance, so it's recommended on late days.
Fix: Moons in Turrets now change distance when Range is modified during Day.
Fix: Deaths on Endless Coffee mode now count for Number of Deaths achievement.
That is all for now. Thanks again for your feedback. Have a good AstroDay! ☕

Hi, Rebels! 🫡
We hope you are enjoying the new Endless Coffee mode. As you know, the new mode is bigger and more difficult to balance than the Story mode, so we are doing small tweaks and improvements based on your feebdack! 🔨
We are launching a small patch with some balancing changes on Endless after Day 21. Also make the Luck a bit slower to increase, because it could break the game too early too easily. Besides that, some small tweaks on Beach Balls/Thunder visiblity, and trying to make Thunders not crash the game eventually ⚡
Finally, we have made another change. When we first released Astro Prospector, we wanted to give some extra challenges for those of you who wanted to play more. That's how we came up with the achievements for Speedrun and Deathless run. With the new mode released, there is plenty of game to enjoy once you complete Story mode, and as of today, the biggest complaint we are receiving for Astro Prospector is about those two achievements, so we are removing them from the game 🍃
We know some of you worked hard to get them, and hope you understand our decision. The achievements no longer existing doesn't erase the challenge you overcome, Space Rebel! So, if you managed to get the 2 achievements, you can enter our Discord server and we will give you a special Discord role reflecting your dedication 🏆
Full Changelog:
Balance: Increased Thunder min. Cooldown from 0.2s to 1.0s
Balance: Thunder Cooldown Reduction Per Enemy Hit from 0.1s to 0.01s.
Balance: Extra Thunders can no longer spawn additional Extra Thunders
Balance: Reduced Beach Ball "Explodes on Hit" chance from 33% to 20%
Fix: Applied various tweaks to Beach Ball; Stationary Damage is now applied correctly
Visuals: Beach Ball now changes visual layer based on size to improve visibility of enemies and asteroids behind it.
Balance: Reduced Luck values on upgrades slightly to make reaching 100% Luck more challenging
Balance: Increased enemy health scaling significantly in Endless Mode (after Day 21) to increase difficulty (should be more funny now!)
That is all for now. Thanks again for your feedback. Have a good AstroDay! ☕
