TOO LONG!
Not really. I think the down key's action and the "WARNING!!! CONVENIENTLY PLACED BROKEN BUILDING" were funny. If you were to make a full length game that sucked on purpose and had things like that it would be great. The shortness makes it funnier, but it's hardly enough for it to be even considered a game. You get a 3 for the humor.
Oh, and you should make those flying squirrel eggs easier to dodge, like dylan99952 said.
