I refuse to believe the second half of this game was actually playtested. I was having SO MUCH FUN at the start, but the backhalf of levels seemingly started to become OBNOXIOUSLY difficult at points. The final boss was so difficult that I was bashing my head on it for over an hour trying to get it, only getting it literally the attempt after posting this (This is edited). Fun game, but the difficulty needs to be re-evaluated at the end.
