Welp, first run it crashed. Once it got working, the mineoid was about 10hp lost before I could even see the screen due to it bumping on stuff. Maybe a 3-2-1-GO style thing could help, or a "Press Enter to Drop" could help with this.
Despite that, it's neat and a very cool concept executed consistently. The ambience is good and the sounds are cool. I also hit escape to pause and it just closed Godot. Even if it seems simple, give playes all of the controls they have and the experience will be better.
Good job though, seriously.
