Thanks! Glad you liked it and were inspired. Pico-8 is great fun. Limits are good for creativity but it's not as limited as a real 8-bit computer in some ways e.g. palette/gfx modes, and has built in tools for sprites/tilemaps/sfx/music.
I've got another pico-8 game coming out on here soon. Cyberjam. Keep an eye out for it.
