Level design is akward. Where all these bullets come from? There are a lot of problems with collisions with bullets and with clovers. I tried to find all, I saw that at the minimap they can be seen even if I didn't explore specific area yet, but last two clovers aren't located at the minimap and I think that's a bug. I propose you to create smaller levels with more details and interesting design rather than big levels with strange speed modifiers put in the level like wall tiles in the bathroom.
