Your game is really fun i love the gameplay , althought maybe a bit too hard i am already stuck at level 2 xDD ,
Maybe decrease a little bit the amount of ghosts that get spawned or make them spawn a little bit farther from the player
there may be a bug when it comes to those charges they get like respawned when you change between worlds or maybe you made it on purpose idk
ps : hopefully i can get past level 2 xDD
