I really dislike the window-teleport. It just feel annoying.
3 was very hard for me. I had to sync it to do the jump - is it supposed to be synced? Maybe I'm just bad, but the following jumps are much, much easier.
6 was really difficult for me compared to the rest of the jumps. The height of the first red bar felt too low, making the jump awkward.Or maybe it was the second one being too high, idk.
Last definitely needs lighting. I had to turn on fullbright to do it. Overall, the map could use some windows for lighting. Also, I would make it so the left wallshot was only high, and the right wallshot only low. That way, it's easier to figure out what to do.
I didn't like how small the initial wallshot was on jumps like 8. I often got behind it, which was just frustrating.
Otherwise, nice map - even though the crocodile scared the shit out of me.
