It looks like the start of a game. You have a start menu that sets the parms of the game, but nothing that isn't already on the ui in-game. The only exceptions being About and Quit. The About item's back button does not function. I think the Quit button should be included in-game. The hand model and watch look good. Maybe have a way to toggle them off when not needed. The readouts are interesting - maybe they hook into the game later on? The height readout seems to be tied to the hand it is on and which direction the palm/back of the hand is pointing. Jump seems to work. Doesn't jump very high.
The only sound I hear is on the menu buttons.
Maybe add something to jump on/over?
