It's a simple and fun concept that was very well executed. I don's know how hard is it to write code for Pico-8, but almost everything that comes out of it is great. Thumbs up for this game!
It's not that hard really, its very good for making simple ideas without advanced physics and stuff (you have to code those if you want to use them). Personally I love the restrictions.
Oh, I know Lua! I've heard about this language when I was watching Source Engine videos I think. Either way, you've made a really cool game and I hope to see you in the next gamejam!
