So I just discovered a huge bug... The Red Slime flinger can move while the game is paused. Though it is under very specific circumstances. Due to the nature of pathfinding, the slimes can get... Stuck if there's a platform they can't reach. So they try desperately to hop back and forth in order to reach it. Though the one exception is the walking red slime sentry. This thing... Is pretty buggy. If you pause while it is flickering between walking one direction and another it will slide in the direction of its sprite.
All because of the overhang.
