Really fun game! I like what you have created with pico-8. The music and story was great and overall I enjoyed the game. Like some other people said, I also felt that maybe there were a few too many encounters, or too often. Other than that this was really great, keep up the good work :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
