Thanks! First time doing game dev and it was fun. Lua wasn't too hard to learn but I'm planning on doing another project with pico-8 since the fantasy-console idea is pretty cool (got a RPI3 just for this reason). Didn't have time to add music since I was away for vacation and I'm treating this game as a stepping stone of what I could achieve.
Your game looks fun; I'm about to try that out!
