A harder difficulty! It's supposed to be a challenge map for a reason. Me and my friend beat it on hard mode with un-pack-a-punch'd weapons. Definitely recommend either adding a new difficulty or making hard mode harder. EXAMPLES: perk cost continues to increase, same with random weapon, maybe a door to PAP, or something to unlock it, more zombie health, constant spawning (timed rounds), constant sprinters or super-sprinters.

Make the wall buys at the start of the map worse and the doors more expensive. Along with making perks 2k. Cause atm the map is really fun but very easy I have beaten it on hard and normal using the first wall buy and am able to keep them at the spawn with ease because the guns are too good and too accessible to say it a challenge map but more of a fun experience overall. Making the weapons scale with the rounds better would be a really nice fix. Overall a really fun map and I enjoyed it a lot

Further from my other comment making the zombies always spawn and not round based would be good as there is no time for grabbing perks and a random weapon meaning more tension late game as you struggle to put them back. Alternatively you can add a boss zombie or something to throw you off but would potentially ruin the maps aesthetic and the idea your going for
