has a bug, if you try to shoot while the cursor is on an object, nothing happens. Would also be more fun if the stuff in the shop actually did anything
There is a lot this physics engine doesn't take into account, and so yes the ball behaves in really unpredictable ways. But that's just cuz we're used to actual gravity and not the completely wrong version that this game uses. If you don't expect it to behave like real gravity, it's really fun!
