This is a remake of Windowkill This game was supposed to be called Scratchkill but it sounded bad, so I decided to call it Windowkill, like the actual game. Use arrow keys or wasd to move. Shoot by clicking or holding (you can't rapidfire). Hit the wall to make it expand. The wall slowly shrinks so be carful!
I'll be adding enemies and bossfights soon enough. I'll also make it so you have to stay in the box because you can get out.
