Hey Azzine,
Definitely like an FFR or DDR sort of game! I would have preferred to use keys instead of the mouse but like you said it was originally meant to be on mobile so that makes sense.
I think the game could be improved with some visual feedback when you hit the target and differs depending how close you get to the center like perfect, good, OK, miss, etc. Also adding a background while the music is playing would add to the experience! :)
Congrats on completing the game jam!
