Hello from Italy!
This game has a beautiful gameplay, the sounds are of the highest quality, the level design is of the best. I loved the small details like the animations of the sprites and the scores that, as a musician, I appreciated infinitely.
I also like that there are various compositions that are played and with a good ear, in the soundtrack, they stand out.
The only thing that in my opinion is to be redone is the final animation of the giant bell, which goes slightly off-sync with the audio and does not work as smoothly as a real bell.
As for the performance of the game it is optimized very well because I tried it even with a very weak laptop and I kept constant and high fps.
Congratulations for the job, wish you the best!
