Very well done. The procedural generation of the levels is just really neat to see. Movement also felt good though I had a couple of issues with the wall run / jumps:
* The vertical wall run / clamber felt good, but it was hard to judge visually whether I'd be able to get up onto a platform with it or not.
* I felt I always wanted the horizontal wall run to go a bit further than it would let me. Maybe it's just relative to the space, or from previous experience in other wall-running games, but I kept falling short.
* The wall jump kicks pretty far out, and will do so automatically if holding the space bar from a previous jump. I kept accidentally wall jumping out into open space and falling.
The environment is very cool, and especially since it's based on a real-life structure. The music and the audio effects are all great. Visually, I did have an issue with the lighting just being too dark generally and thus finding it difficult to make out where I needed to go next sometimes. Whenever areas were lit with the lighted windows, it was fine, but areas without those could be difficult to navigate.
But overall, very cool and inspired game!
