This game was beautiful in its own way. The sense of scale and loneliness set by the opening text and the level design was palpable, and I really enjoyed the atmosphere.
Mechanically, the platforming felt a bit clunky and imprecise, although I only ever fell off a platform one time throughout the entire playthrough. The time slow/reverse mechanic is also a fun idea, although the slow wind up and wind down made the ability feel very unresponsive. The level design was subversively good, as I almost always thought I was lost, but I was always going the right way anyway, which added a lot to the atmosphere of the game.
The notes scattered around the level were a bit annoying unfortunately, as they darken the entire screen to the point that its hard to see where you are. They each had a mountain of text that would mean I have to stop playing the game entirely to read, so I ignored all of them. The opening text was well paced though, quickly establishing the setting, and letting you actually see that setting soon after.
