Thanks so much for your feedback! Those were some very nice points we'll be working on very soon (rn we need a rest lol)
Regarding point 3: The game core mechanic is supposed to be based on sound and paying attention to sound. The idea is for each ghost to be "killed" by a specific bell that matches the sound that particular ghost makes. Do you feel that part wasn't clear enough in the tutorial or something? We could work on that
