These doors take 5 whole seconds to open and close. They also z-fight with the world around them. It's often best to make these go very fast as to not hinder movement of the players. Also spawn is really bright.
This lip is too high to walk up back into spawn, you need to jump in order to make it back in.
If anyone makes it into mid, they have a direct sightline into the enemy spawn.
Brushwork like this is far too angled to cleanly walk up it. 45 degrees is the maximum walkable angle - anything else will need to be jumped up in order to traverse.
A Soldier can not make this jump without rocket jumping. A Heavy will fall to his death. Almost certainly any class that isn't a Scout or doesn't have extra mobility will not be able to make these jumps.
These two paths to the intel can also not be traversed by classes without extra mobility. You'd need to rocket jump, double jump, sticky jump, flare jump, sentry jump, or build a teleporter on the raised ledges just to get across - some things that aren't readily available to all classes.
Also, the brushwork has some general issues - most prevalent by the structures of the arches and stuff like this at the bottom of the pit. The HUD also appears to be broken.
Hopefully these things can be addressed. You
can get something playable out of this, but it needs more work and dedication.
