This game is a lot of fun. Unfortunately runs with a pretty low framerate for me on Linux. Might be worth getting new ammo at the beginning of a stage.
Thanks for trying it. It's a shame about the framerate. I actually tried it only on PC and MAC since my very old linux machine is unable to handle Godot 3. As for the ammo... It's part of the challenge to manage it :) Then again... Daisy asked for it :)
