Up and Down Keys to move Space to shoot (you can shoot every two seconds) Survive long enough to proceed to the next level. On boss levels, destroy boss to proceed to next level. The three small cats at the top of the screen are your lives. There are a total of ten levels, two bosses. The first boss has a health bar, but I have not added a health bar to the second one yet. The second boss has 8 health. More levels are going to be added soon.
I take no credit for any art. FEEDBACK GREATLY APPRECIATED! UPDATE: Added two more levels. I have not tested level 12 yet, so if there are any problems, please notify me in the comment section below.
