I believe this is my favourite game of the jam! A deserving winner.
A beautiful idea, excellent storytelling and good gameplay.
I would only change the controls around. Space to attack and W to jump. Would become a one-hand game.
Perhaps the player movement could be worked on too. Test a few things out, at the moment the controls are just a little too floaty somehow.
I really hope you consider doing something more with this game and perhaps fleshing it out to more levels, different animals and areas. It's a beautiful idea which would translate extremely well to all platforms (mobile included).
Extremely well done on the game!
