Cute game! Love Watty's design, he's so cute! And the idea of him trying to put his glass back together is really cool~! Also like some of the platforming elements, e.g. enemies with repeated, non-random patterns so you can learn how to pass.
I think there might be an issue in lv 3 though - many of the jumps appeared impossible, i.e. the player jump literally could not reach it, even if I ran first.
Would be interesting to see an expanded version with more artwork added-maybe showing the environment he's hopping through!
