You should use this tick regen prefab for health (it can also set soldier hp to just 900 so you can remove all the various overheal triggers):
https://jump.tf/forum/index.php?topic=3205.0 . You can also delete all of your func_regenerate after doing this and just place 1 big one around the entire map. There're a lot of random small places you don't get ammo regen which can be a bit annoying
If you care, the jump towards the beginning with the 2 speedshots and the ramp you can do just by jumping off of the end of the ramp
The forest wallpogo jump has broken nonade on half of the grass. Also, if you're going for T3 I think this jump is too hard. Either the walls you pogo on should be a lot bigger or remove the corner, or both probably. Your button on this jump also moves forwards with the platform for some reason which I don't think is multiplayer friendly. the button also doesn't really add much so if you wanted to you could just remove it and not worry about it
After the steve climb jump you have a lot of missing texture. you should probably be using compilepal (
https://github.com/ruarai/CompilePal/releases/latest) for final compiles if you're not already, it is very good at packing textures automatically.
The teletriple thingy you should either turn the player around to face the rockets or move the last platform so that the timing is automatic. Also, the last hole with a tele (the one you triple in) the tele is flush rather than sticking down which is annoying to bonk, you should probably just make the frame around the brush func_illusionary so that you can't bonk it. Also, the tube after that you get teleported into has many missing textures.
I don't think that last is T3 either but if you made the wallpogo jump easier it might be okay since it is last.
Your bonuses should most likely all bring you back to the bonus room, not spawn, otherwise you have to noclip back to the end CP after finishing one to look at another one. B1 is missing regen but seems fine, though I'm not sure what the random nonade on the floor is meant to accomplish. B2 has a missing texture at the end and has weird nodraw on the back of the surf ramps for some reason. B3 your telehop is completely broken because the levels don't face the same direction, so you keep speed but going the wrong way and immediately bonk the wall behind you in the second room. To fix this you can just rotate one of the rooms 180 degrees.
