Very polished game, well done guys! So many good things I could say but perhaps my faves are: the ageing of the character which changes their skills, and how the artwork fits so well together.
I also had trouble with some of the platforming aspects of the game, once I'd worked out the puzzle I would still hit spikes etc for actions I thought should be okay -- perhaps I can blame HTML5 lag. :)
Overall super impressive, highly rated from me.
