Contrary to what the others were saying, the controls in the game were pretty good. The object here is not speed of movement, but placement of objects. The way "Eric" continues moving in a given direction on the trampoline adds challenge. Being able to move objects while you're standing on them would ruin the point of the game in the first place.
That said, for the type of game you've created here, I can't find much lacking. I give you 6 out of 10, because the game is more than mediocre (a 5/10 score), but not enough to really "wow!" me (an 8/10 or higher score), and +1 point because I thought the title was a nice variation. It could have been something like "Reach the Exit Game," and I probably wouldn't have tried it out.
Suggestions: Perhaps a little music loop or something would freshen this up.
