Rivals (flash) portal for innovation on the puzzle platformer, but alas only 18 levels. I want to see more objects, too! A good one would be a 5 sec invincibility/ghost item as that would allow for combos with pickups. I would also suggest eliminating the laser and forcing the player to touch items, both making the levels harder while making the concept easier to grasp.
But as is this deserves 4.
