A good challenge - however the "level completed" noise hurt my ears, alas when I turn my volume down I can't hear the music. Nonetheless, good game.

I like it a lot. I like how you can choose any level, and it still keeps track of each completed level. I enjoyed how it starts off easy so you can get the hang of it, then gets increasingly harder. The music is great, I like how the beat makes you want to keep going.
Great game.

Simple, challenging and addictive. Well executed.

There is a glitch when you press HINT on the first level of Easy. The challenge was good. But In my opinion It could use more content, because you want to make the player want to come back for more and find something new or feel like they achieved something. Keep up the good work and I'm sure it will be successful.
