I'm glad you kind of liked the music because I was forced to do something quickly (I was running out of time so badly). I agree that it becomes too repetitive, especially since it sounds a little too aggressive. For my next updates, I'm thinking of composing the proper musical tracks.
I LIKE your challenge, now I want to try making sharp letter too, ahahah. Glad you had fun with the game. I'm thankful for your opinion, it means a lot!
