Instead of using Godot like I normally do, I've opted to make a PICO-8 game this time around. I'm only a few hours in, but here's my progress so far:

My interpretation of the theme is a game where the amount of safe space for the player becomes increasingly limited, because the cave becomes more flooded with every three steps taken.

I assure you, the code behind all this is exactly as janky as you think it is.
