Loved the visuals, especially the chasm, and the shifting landscapes. Just had one note about it, when climbing the ramp to the energy source, it doesn't look really clear that you are climbing something, and I thought it was a visual bug until I saw the screenshots of the game. For sleeping, I think it would helpful to add a small sleeping scene, it doesn't have to be complex, just something to show that the character really took a rest, like the screen fading to black and then back or something like that.
