The game is really really good, and it's impressive you managed to pull that off for the jam ! The OST and sound design is very charming. The graphs are more than enough. The AI behind the hero is very impressive. I have more problems with the momentum of the character, I fell way to many times in spikes due to it. And I always had to restart from the begining (I didn't found any checkpoint). I preferred to stop when I died after the second part in the factory, trying to save my brothers. So it only lacks checkpoints so that everyone can appreciate your game (and maybe rework the momentum of the character).
