Nice map, really liked the look of spawn when i first joined.
Some thoughts:
J1: walls seem weirdly long (I only ever use the first 1/4 of the wall when doing it), the jump is fine though
J3: You can just use the right wall at the start but I assume you start left wall because it's closer IDK.
J7: wall texture is a bit annoying because it's hard to gauge speed with. probably just me dw about it.
J8: Little bit dark in the pogo area, but works good.
J9: the walls are very low for a triple, often overshoot 1 or both.
JAll: The tele destinations all seem really far from the start points. No health, rockets hurt :c
Anything not mentioned was ok imo. These are just my dumb thoughts playing through it a few times :3
Overall cool fun map!
