The only real issue I noticed is that one of the weapon spawns seems like it should be a jumppad, like the other one that looks just like it, but it is not. It really feels like it should be, and I am not sure if it is a mistake, or intentional. Other than that, it was a fun map. I personally think about 5-7 players would be about perfect for it.
I like different and eclectic maps, and I recommend this one.
As you mentioned, it's really easy to fall and die. I agree with you about the width of the walkway.I didn't have careful plan before making this, so, in progress of work there occurred some unreasonable(undesirable but essential) places that is hard for me adapting to something balanced.
Now I regret not listening to people's suggestion like you.
On the other hand I did not think of my map as worthy of beta-testing.(o_O)
I apologize to tiger-on, fileplanet and those who had downloaded my map only to find sky texture is missing.
I know it's too late.
