Really fun to play! The sprites are really nice, and the background could look equally as polished with some more time I suspect :)
The difficulty curve was fun but still challenging. I think that it's not particularly clear what the goal is. I figured out that the keys opened the blue doors but only by accident :P (then again I am pretty dumb so might not be an issue).
Overall really polished for a jam title, excited to see what comes next :)
