About
This is my first pico8 game, and was made in around one month. Once I had the prototype movement working, I realized how much fun I was having just bouncing around the test area, so I decided to flesh it out with additional levels and a tiny upgrade system. I'm not sure I *can* layer any additional player actions into that singular button.

I certainly ran headlong into pico8's cozy constraints. The project uses all 128 sprite tiles, the entire map area, and 7922 (out of 8192) Lua tokens. It's a tight squeeze, but I made it fit.
