I know you said the main speed (which I assume was the straight shot from base to base trough the upper middle) was OP, but I think most of it felt fine. Rather than trying to find way to slow that path down, it'd probably be better to streamline the other routes. You could potentially chokepoint it a bit more so it's easier to control and not as viable to speed through. Could also remove the hole in the glass above the flag.
The paths to the 2nd flag feel like they're just intentionally made to be awkward. Fine for experienced players, but they're going to be really clunky for new players and bots to navigate. You could, at the very least, change the box next to the ramp to a set of stairs and maybe add a ladder to the path the barrel jump goes to. I don't believe main objective should be behind trick jumps.
The tunnel texture did not appear to be included with the zipfi... wait, rar file? Who are you?!
I'm not sure whats with the mist brushes up by the autococker, copied from Tini's map. Is there a reason you want it to look like you can't pass through but you actually can?
