So I'm mixed on this one, I think, for the most part, that the puzzle elements, world interaction and level design are pretty solid. However, I think the movement is pretty rough. In a first person platformer, especially one so precise, air control is a real issue. I felt like nearly all the times I either fell or died were due to the fact that I had so little control of my movement after leaving the ground. This wouldn't be an issue in a game where the sole focus was something other than super precise platforming, but it is here. I wanted to see more of the game and mess with more of the puzzles, but the repeated punishment for things that did not feel like my fault were too much of an obstacle for me.
