The difficulty scaling needs some major work, especially on stages with less checkpoints, the flow of the gameplay feels off.
Myself and others have found a few minor bugs, inconsistent triggers, and places you can stand where you shouldn't be able to (on top of ladders).
It's very confusing trying to figure out where to go on your first run, and the mixture of brushes with and without collisions doesn't help. I was watching someone do a run who had already set a time, and even they were getting lost.
These are all minor problems that are very easy to fix, if you want me to point out the details and give you a little help fixing them, feel free to contact me.
This map would really benefit from a v2. With a few little adjustments this could easily be considered one of the best maps out.
