I like the concept and the visual style, they both remind me of Rayman with the freeing of prisoners in cages and the chase.
There are a few issues that I would like to point out to you guys, first the character running animation looks a bit jerky, like he's vibrating back and fort while running. The jump feels too floaty and slow, I think you wanted to go for a fast game but something as important as jumping actually slows you down here. Dashing is really good on the other hand.
Fighting enemies seems pointless and a waste of the distance I put between me and the chasing monster. There's no bonus to beat them and no malus to avoid them, which is also really easy. Also, the over abundance of hearts means that I don't even need to worry about them hitting me. It's too bad because the enemies looks too cool to be skimmed so rapidly.
Finally, there are too many torches. Basically the only reason I was dying when I realized I could just speedrun was messing up the jumps/dashes between the narrow platforms/pillars.
I hope you find this feedback useful, I liked the game and would love to see its full potential. Good job!
