This game is amazing, its a real gem. Even got it to work on my Linix retro device.
There are only 2 problems that keep it from being perfect for playing on it:
1. Game over screen cannot be controlled with keys, only mouse! Please add them!
2. If you set in Godot settings to use Aspect as "keep_height" it would allow devices with 4:3 screen to zoom in to the height and cut left/right sides of screen to fill whole screen while not hurting 16:9 screens.
Thank You for making this addicting game. Good luck with it!
