Use the arrows to move Mimi! Don't touch the beetles or ghost! The ghost can go through walls! The ghosts can hit you even when they are semi-transparent big blue bug: waits a bit a rush down a direction white ghost: follows you and goes through walls, when they stop being transparent they are faster. Blue ghost: follows a hard to see white bug that can't hurt you (but the ghost can)
just changed a bunch of random stuff, try making something like this yourself, its pretty easy. This game was most likely made by using a tutorial in a book made by scratch, I had the same one!
