Use W and S or arrow keys to move your scratch cat. There will be bullets coming out of the scratch cat. You will have to hit the "Aliens" with two bullets to kill them. There will also be power ups. It will take 3 bullets to use the power up. There are still a lot of bugs. - The arrow power up makes it so you shoot bullets faster for 10 seconds. - The Flying Up scratch cat makes it so you can one shot enemies for 10 seconds (not tested) - The Heart power up gives you one more life. Be sure to star and heart the project!
I mainly used scratch sprites, though I did use text from cooltext.com.
