This plays kinda similar to the Hamster Fitness minigame in Professor Layton and the diabolical box! In that (if you haven't played) you are given different objects which the hamster is either attracted too or repulsed by, usually given a range of tiles etc. I think if you were to expand on this then different objects would be a must. I like what's there, but it took me way too long to figure out that the switch was a switch!
