SERIOUSLY!!! PUT THIS IN THE GOGGLE PLAY STORE!!!!!!!There are 2 problems with games like these in the app store: 1. Since people don't have a random generator feature built in, they have to invent each level, limiting the number of times you can play a new game.
2. You normally have limited variables making the game limited in skill.
This game has countered both those problems while creating enough of a challenge to keep me playing (main point of a game) while not being so engaging that you can't put it down. The recipe for that is a game where I would gladly play it whenever I have a chance.
The music you chose is awesome as well! It seems to me to be an alpha brainwave study music, however, what I find with these kinds of music is that they become... tedious after continuous play. To counter that, I'd add two more options for the music, as well as (since no one else does it and it would be great) an option to play the music you already have on your phone.
