This game was very interesting.
I feel like the wall detection was a bit off, but I'll chalk that up to Unity's WebGL jank. I really enjoyed exploring this world, reminds me of some Mirrors Edge custom levels I used to play. Overall, very nice, graphically charming and interesting.
Good work!
For some critiques:
I don't think pressing the space bar is what sould activate wall running, I think you should go more in-line with other parkour games and place walls next to the standing position of the player so its easier to traverse the world.
Controls could be tweaked a bit more, collission needs the most work, I ended up getting stuck climbing up certain walls.
Sound would really help give this a more aetherial experience, game feels quite empty without it.
