Wow! Very nice.
I really liked the entire style of the game in general, the pixel art, the music, AND the sound effects.
(TIP: If you want an even more retro looking game in godot, you can go to project settings/window, change the viewport size to something small like 64x64 or 128x128 (the resolution I used for my game), then enable advanced settings and set the window size override to a multiple of the viewport size you chose. This removes pixel art issues like sub-pixel movement, or particles having a different resolution compared to your sprites)
The concept and gameplay are also very nice! I enjoyed scrounging about in the ever-moving mazes for scraps of Burger.
All in all, great job! i really enjoyed your game.
