Thanks for the kind comment ! For the music resetting, I debated it for a few second. Since the tiles close themselves following a predictable pattern, I thought It could follow the music (like Beat and Shape on Steam, you should check it out), but yeah didn't had the time. In that implementation, putting a DontDestroyOnLoad would of been better. As for the bombs, you are right, they glitch sometime, I will have to check them out.
Thanks for the detail feedback ! Just rated your game!
