Thanks for checking out the game! We are currently working on some requested features already! We hope to get them out over the weekend. - Rework how the weapon upgrades work. Currently they're on an per weapon basis. We want to change it so it is now global. So if you swap out weapons after upgrading for a little bit, the newly equipped weapon will also have all of the weapon upgrades! For maximum carnage of course :) - Add controller support. Some users have requested controller support, so we're making sure all of the UI is responsive with it. - Add Steamdeck support. This partly ties into the controller support. But we also want to make sure everything feels good while playing on the Steamdeck - Adjust difficulty scaling. Some of the difficulties are harder than what they should be, so we're going to be tuning it a bit. - Performance. Most of the performance drops happen when the big ball of Zombies collide with each other. We've been working out ways to better handle this.
