I think the concept of giving things up was interesting, and using it as a key to move on does follow the metroidvania aspect. I think the combat was really annoying though, I couldnt figure out how to fight the melee ones without getting hit in return. I got up to the second key on my farthest run, I think if you added a way to heal, maybe there was I just didn't find it! Also an in game tutorial would be good, just putting them on the page isn't as fun! I liked the dash, it made me feel free lol, and the art was pretty cool. Also, escape closes out the whole game, idk if this is on purpose but it made me lose when I tried to pause mid run! Great job overall!
