I really, really liked the game. I spent the last two hours just getting 100% on the levels, but sadly I wasn't able to finish the last level. I had gotten all of the stars and the download coupon, but the control rods 1 and 2 got stuck and wouldn't slide out like the other four. If it's possible, you should probably widen the control rod's resting area or make them thinner so this doesn't happen to future players. Still loved the game, great job.
