a little too easy me thinks

Sounds are annoying and gameplay is repetitive. The best way to do things like this is to not make it an immediate challenge, but have it easy at first and get harder as it goes on. But, it's a cool concept and if you expand on it it could be a great game.
Overall, nice work but there's room for improvement.

Edit: You did exactly as I said and see what difference it makes! Thanks for listening.
