    A New Threat Emerges!

    💥+New Game Plus+💥We've been listening to feedback and working for a while since launch and the biggest feedback anyone has had is that players love the game so much that they want more game to play!🫡Message Received!🫡With that we'd like to introduce New Game Plus ...New Enemy BehaviorsNew Balance NumbersNew Achievements!In addition to that we've compiled several points of feedback and made improvements to ...Optimizations for smoother gameplay, especially later levelsSome players reported hitching and slow downs when enemy waves got truly intense and we've made some changes that should mitigate if not remove these issues in later levels.Right-Click to max upgradePrestige levels is part of the game and common in the genre, but clicking many times can feel tedious and agitate some player. NOT ANYMORE! Right-click any upgrade to maximize spending in the upgrade and instantly reach max level if you have the resources.Steam Cloud IntegrationEspecially with the increased content of the game, players wanted the ability to use cloud saves to pick up where they left off. We're still verifying the functionality, but Steam cloud saves are now available and automatically sync when players exit the game.More informative tooltipsWith different upgrades having different maximum levels players wanted better context about where they were with regards to each one. The upgrade popup now includes that info.Better readability of upgrade descriptionsFont sizes and readability have been improved on most descriptions so players on small screens and Steam Deck can have a more comfortable experience.Several bug fixes Supply crates drop earlier in rounds to make them more accessibleAuto-turret now prioritizes the supply crate to ensure its destructionVarious UI controls not quite functioning as intendedAchievement adjustments to make them more reasonableMANY MORE!A Heartfelt ThanksFinally, thank you to everyone that has played the game, given feedback, left a review, or been involved in any w...

    Achievement and Balance Tweaks

    Minor Patch NotesThe "1 Million Bugs" achievement requirements have been reduced.Players did the math and rightly pointed out that the required time to achieve this achievement was well beyond the intended play time for the launch content. The achievement has been reduced to 100,000 bugs and been renamed so that we may never forget ;).The Care Package dropped by command now appears earlier in game rounds.There is still a range of time where the package can occur so that it isn't standard across every round, but players reported frustration when the package could potentially show up 3 or 4 seconds before the end of a game round and they didn't have a chance to take advantage of the upgrade that they'd purchased. The base health of the care package has also been reduced to better allow players to break the box without having larger damage upgrades of late game.Other minor balance tweaks and bug fixes.We are still adjusting the balance of the game slightly so that players feel engaged with the game as they scale. We don't want to take away the late-game power that players feel, but adjusting some health values for late-game enemies helped them feel more distinct in their respective roles in the game.

    🛠️ Post Launch Updates 🛠️

    🛠️Post Launch Updates🛠️We're super happy to see players playing and enjoying the game and voicing their opinions on how we can make the it even better.We've just finished pushing the first update to resolve a few issues that players have reported listed below ...ACCESSIBILITY: Enemy damage flash can now be adjusted in the options menu (gear button)Players reported that flashing enemies as they receive damage caused visual discomfort and an accessibility issue. This is a top priority for us and we don't want anyone to be hindered from enjoying the game so this can be reduced in the options menu.Balance: Max levels of some economy upgrades have been reducedSome players have voiced concerns that the late-game economy of the game feels too accelerated and the later prestige levels pass too quickly. We've reduced the max scaling potential on some economy upgrades to hopefully pace the end-game better and allow players more time with the later prestige levels without hindering the ability to reach those later prestige levels.UI / Quality of Life: A confirmation message has been added when clicking "New Game" in the event that a player has save data that will be overwritten with starting a new gameSlightly increased font sizes on upgrades info popup for easier readabilityReduced opacity on fill bars for conversion UI elements to improve readabilityBug Fixes:Conversion Factory achievement should now be attainableSteam Deck should now properly award achievementsThe Laser Automation toggle button no longer overlaps the button to start the next round
