Would it be possible to increase the sky in this map, when you are at the grenade launcher it's impossible to use a boost jump there...
It might also change gameplay a bit (movig from side to side over the walls, or worse: walk over the walls)
Maybe they can be fixed by putting spikes on them and making it a killzone ? Or maybe at a force to push one off trying to walk or jump over them...
Don't know if you can it a real "bug" though....
