I liked the bell mechanic, but starting level 3 it is just to hard: Even knowing where the ghost is spawning i have no time to go back to the bell... The fact that you need to be "frame perfect", it breaks the immersion and reminds me i'm in a video game. Maybe it would be more fun to have a slower ghost, but the bell is not always at the same place so you have the stress of searching instead of playing well ? Good job overall !
