Overall I really enjoyed the demo, the art looks great and the gameplay looks promising.

For feedback, I would personally change the button you hold up to the rocky walls, maybe for the left trigger instead of the map. I've read you're planning on makeing changes so that's great, only wanted to share my opinion.

I would also suggest making the sfx for the sword to feel a bit heavier because, for me, it feels lightweighted compared to the big sword relative to Tofu. Also the music feels a bit repetitive and lacking of character I think there's room for improvement in that area to give more character to the game. Maybe some kind of medieval music?

Also, I can't add images in here but on the final jump in the crypt (the two moving spikes). In the smear frame the texture of the wood is missing and creates a weird effect. Just wanted to point it out (probably because I got stuck in that jump a couple of more minutes that I should have xD)

I'm going to back it on Kickstarter now, hope to see more content soon!

Great job :)
