I made a small game called picoroguelike with the intention to learn how to make games with pico-8.
The "virtual console" always dragged my attention with its colors and charm music (ironically that is what my game lacks the most), but my heart is one of a programmers so making it a bit harder and dirtier that it needs feels good.
Anyway, make sure to give it a try and tell me how you like it :)
