Use the up, down, left, and right arrow keys to move the cat to the portal to advance to the next level. Nyan cat is controlled using W, A, S, D. (unlock Nyan cat by playing the first level) (still being edited) (Nyan cat is like tails in sonic 2, it is invincible, and just for the pleasure of playing as, Nyan ;3)
There were problems that occurred in the making of the game, one was the inability to make inverted controls after touching a sprite, and making the cat move as your hand moved (have some fixes in mind), and the portal being in a specific place. I was able to make a rainbow stage that is laggy, yet pretty, so it is slow after you get past the first level, but it will speed up as you go. And I was able to change the colors without the cat going to the start no matter what. I think that is about it. (credit for the idea for the internet meme Nyan cat gets the credit for the idea of the cat, I am merely using it for a rainbow effect, so if anyone asks I made the sprite in the game the idea goes to its owner)
