Er… Use the arrow keys to rotate the cannon. Use the space bar to shoot. The nightmare essences(or tadpoles) give you one point while the feline ones(the two things that look like cats) give you three.
So this is another progamming class project, but I'm still working on it. My sister reeeally wanted me to post this now… SO, UH… THIS THING IS SUPPOSED TO BE CASTLE DEFENSE. When I showed this to Shimmer aka KoolKirby(my sister), she immediately burst out laughing. And then I started laughing. NEITHER OF US CAN TAKE THIS SERIOUSLY ANYMORE. But then again, how can you take a hyper cat riding on a floating cannon and shooting at things that could only be described as cat and tadpole silhouettes zooming around the screen seriously? I should have thought this through. BTW, the "hero" of the game is my fursona, Blizzardfoot, or Bliz. She's a pretty old character with a bit of a simple design, but I still luff her <3
