Thanks for the suggestions :)

This is my first 'succesful' attempt, I messed around with the mod tools on multiple occasions before, but usually gave up in fury. This is the first time I kept trying. So yeah, it definitely can look nicer, and I'll definitely try that, but yeah xD

I'll try to fit more perks. Custom ones sound quite difficult, since I'll have to model them myself, or find existing ones online, but I'll try to see if I can just reskin an existing one.

Mhm, the running around in circles idea sounds rather interesting, I'll definitely try that!

I'll add more wall buys, probably some in other rooms.

It wouldn't really have been useful to put multiple boxes in 1 room xD

Custom weapons, again, the modeling isn't my forte.

Oh right, I thought about the gobblegum machines multiple times, but I forgot adding them after all :facepalm:

An easter egg sounds interesting, but I won't confirm whether I'm gonna add one, since that way it wouldn't be a surprise.

And the part about the zombies getting stuck: If you mean in the zombie spawner area, I saw that on a different one window map, but I hoped it'd be fixed due to the bigger spawn area. I guess not, I'll try again xD I didn't get high enough to find out about that, because it gets repetitive alone.
