Cool little game! Had some trouble with it, but that's to be expected I think. Here's a tip for future submissions:
If you continue to use Godot 3.5.x for 2D games, make sure you turn on Use GPU Pixel Snap in the 2D rendering settings in your project settings. Not having this is what caused your TileMaps to not have perfect alignment, and occasionally got what looked like separated tiles.
That's pretty much it! I have nothing others haven't already said, so good work and I can definitely say we all hope you continue submitting games to the jam! This game has a ton of potential.
