Finally got down and did this... dunno a name for it.
I believe it's 12 colors+transparency. I had a hard time getting a lot to fit in such a small area with such a large scale on the setting. I also had a problem thinking of how to do the gerbil ball... so I ended up 'cutting' it in half so you could see inside it, as I felt it robbed a lot by not actually showing the gerbil.
So, you're a gerbil(I think that's what it is), that has been left in your ball while everyone went out. The point of the game is to travel through the house in your gerbil ball and make it back to your cage where you'll be safe and comfy. You'll go through various rooms, basement, child's room(mock-up), kitchen, and the list goes on. Anyways, the one button is to jump. You'll jump depending on how long you hold the button. Also, you'll keep going in a direction until you hit a wall, if you hit a wall you'll bounce and go in the other direction. The longer you go without changing directions the more speed you build. Last but not least, the 'scoring' is gaining pellets. You start off with a certain amount of pellets on each level(resets on each level), and gain them while you play. Your pellet count continuously drain while you're playing, so you have to keep them replenished by being fast and accurate.
