Not as good as your other game
It wasn't as good as the balloon game, because this was a pretty lame platformer. To prevent cheaters, on the first frame put:
Stage.showMenu=false;
That prevents people from right-clicking and pressing "Forward" or "Play".
I didn't like this, try to add something new if you're making a platformer, because this was pretty crap. Good luck for future projects.
I voted 2 -- if it was under judgement, it still would have been a pass.
