The controls take a lot of getting used to and I liked the boss fights a lot even if I never beat marisa. Any curved surface of terrain or jutting piece of geometry can be jank and get you stuck though which makes marisa rotating lasers paaaaain, especially for someone who has not mastered the control scheme of the game. Plllllleeeeeease, if you have a game where mouse is important for lots of fast clicking and moving either force fullscreen by default or lock the cursor to the window, I accidentally closed the game in the marisa fight and had to watch my friend go through the rest. Fun game, fun concept, I would not want to collect all three keys again but would of liked to go through the bosses again since I closed my game accidentally :( . Once you realize that you can parry bullets, the game gets *so* much more manageable. Thumbs up
