The game is nice, but it goes up in difficulty way too fast. The skeleton boss was fun, and I really like it although he is a lot harder than the first boss. I wasn't able to go past the second boss because of it's really weird hitbox. I was able to defeat one of the snakes, but when I saw another, I just couldn't bring myself to do it
Also, I have trouble seeing the theme of Exchange... maybe I missed a mechanic somewhere?
Otherwise, the game is good looking and I like the small cutscenes.
