I like the Idea but i would have done spawners with 'random' setting so there wont spawn too many items, and spawncannons with keys if no key spawns in the spawners.

If you really dont want to do that, I would love to make a similar map myself, giving u credit for idea :)

after many items, the game runs not at low fps, it is slower for some reason. Like before death ray needs 4 secs for shot and after many items it needs 9 secs - i dont think that that's a problem with the players computers...

I've seen people stuck in there for 3 minutes easilly. Even my PC slows down after 2 mins. Why not put a key in each room after 60 seconds or so?

As for large weapons getting stuck in the blocks adjacent to the walls, I'm sorry but I can't find a solution to this aside from redoing the whole map or removing those spawn blocks. The game itself is quite riddled with bugs that can get in the way of successful map making.

This is the first I've heard of lag issues, might be a problem with the players' computers rather than the maps. Most of the full server tests I've done result in at least one player getting a way out in under 90 seconds.

90% of the times I've played this map, people just quit because no one can get a key before the whole game lags from all the items. Should set a timer for a key to spawn in everyone's room.

Rocket launchers get stuck, so no

Rocket launchers also break locked doors. In addition ot getting out quad lasers and death lasers and be used to attack ducks while still locked in the cell.

It just the key to get out then?
