Left arrow moves left. Up arrow moves up. Down arrow moves down. Right arrow moves right. Space attacks. Right, Up, and Left strong attacks. To advance to the next level, click on the colored orb. A, B, C, and D keys block. I recommend full screen.
I would like to thank my brother, since he tested it. If it is glichy, I´m sorry. I´m not the best coder. There will be a second game that would be better. Enjoy!
