This loop is perfect. I had it running for hours and never got tired of it. Very catchy, easy on the ears and speakers :)
The off-key bells also set off a horror Christmas game signal in my head.
A child hears a noise and sneaks down the stairs to the living room, expecting to see Santa. Instead, he sees a warped shadow placing presents under the Christmas tree. The shadow turns and says: If you had been a good boy and slept like all of the other children, I wouldn't have to kill you. And the shadow reaches for the boy. Then the game turns into a side-scroller obstacle course of jumping and ducking. The Shadow summons presents and various toys that do certain things, to fall from the sky, and if you run into any of the obstacles, you are slowed down. Eventually if you run into too many obstacles the shadow will catch up. The character can never escape, and the game is based on running as far as you can every time. I suppose the player could obtain a currency over time to grant them power-ups, and make it easier to get further faster. Tis nothing truly ground-breaking, or original in the game department, but I think it would be a fun twist :)
