I like your comments. I wanted it to be unique and not quite like any other game before it. I also wanted it to be challenging but rewarding like the old school games. The controls are simple enough that anyone can play yet not everyone can master.
Regarding the sounds, I am experimenting with putting in notes when you click but strangely enough it was much more annoying. It was like the same song playing over and over again while you get frustrated trying to pass the level. The current two sounds are far less distracting. I will play around more and see what happens.
Glad you guys like it! Keep playing though. There are more surprises on level 8.
