Some nice ideas, it's just a shame that each mechanic is only used once then never seen again because the game is so short! It would be nice to see them combined, for example using the jump pad and shrink together to jump into a small hole. I didn't really get the 'shrinking to the quantum world' part, as the character only seemed to shrink to the size of a small child, not exactly quantum. I like the voiceover tutorials, as it allows the player to keep playing, which you can't usually do if you're reading text.
