This is definitely my favourite in the Play category, and I'd be stunned if it doesn't win 1st place there. I'd love to see this developed into a full-length game. There's some rebalancing that should happen, as the previous comments have discussed (I've gone through that tile puzzle more times than I care to remember), but with some tweaking, this could be something special.
There's some really crisp sprite work in here as well - I love the character design to pieces, and I would probably buy a plushie of the main character. Good sound design as well. Great job!
