The background track was perfect for the pacing.
I also had issues with the ledge grab animations and sometimes even getting it to trigger. Ultimately I found it easier to forego the ledge grab, let myself slide along the surface, move off the wall and double jump back up to clear obstacles. I had a little bit of trouble with identifying some of the traps (the music made me want to run, but I had to slow down to search before making jump), but I enjoyed the overall art direction immensely.
