Wow- cool art and sfx! I got a bit of a Cave Story vibe from this. I can't believe how expansive this game is for a jam, enemy variety and map size were crazy! Well done!
It took me a while to figure out that you could click to attack which may have colored my opinion a little bit, I eventually saw the help in the background but I think it could have stood out more. I also just had trouble in general figuring out what was background vs. the foreground sometimes.
I got a bit annoyed having to crouch to pick up the currency- I'm not sure it added much over just auto-picking it up when you were close. It didn't seem like you'd ever not want to pick it up?
Overall really impressive work!
