Wonderful music and some very well implemented controls. Came out the other end wanting more, so that's a thumbs up from me. Even on my first playthrough I could really get a flow going; excellent work there.
Minor quibbles:
- The dangerous 'water' could be a little more visually distinct. As it is right now (a black transparent layer over the 'walkable' grass texture) it makes the pits look like slightly dark areas you should be able to reach until you stop and closely examine them. Even swapping the grass texture for the rock texture in the pits would have gone a long way to clear up that confusion.
- The sudden halt to the jump when released early feels a little jarring
- While I could stand and adapt to the wide FOV it could still get a little nauseating at times, mostly when standing still and rotating the camera; it can feel almost fish-eye at times. I can see people having issues with it.
