A couple things I would do is make sure the songs sound how they are supposed to. They just don't sound that similar to the other songs in my opinion. Another thing I would also do, is try to make for people on computer where they can use their keyboard to tap the notes. Reason being is because some people don't have a mouse for their laptops, and the mouth on the laptop is hard to click fast with. Other than that, it is a decent game overall.
