It is super cool you managed to make a gameboy game for this jam!
The graphics are nice and functional and it's a clever solution to have faraway tiles disappear into darkness. I really liked the smileys on enemies during combat, it made it very easy to see what their health and status was.
I did wander around a bit too aimlessly and get lost - I think a map would be great as I'm just not committed enough to making my own on grid paper these days. Some nice gameboy music would also be really cool, but I know this can be tough to implement and something like LSDJ use up most of the gameboy's power when playing songs.
