Timeline

Butt Monkeys of Alcatraz

Kind of nasty. Lots of ways to die... Personally, I found it distracted me from the true point of a net level (killing your friends), but some folks like this. Well-constructed, anyway.

Canon Food v1.1

Small and deceptively simple. Very nice flow. (This version fixes a small bug, adds a few tweaks.)

Crown of Worms v1.6

A little strange-walls hanging here and there, doors designed not to open, enemies you can't get to-but for a small game, the flow should be okay. (Update is mostly tweaks.)

Disco Inferno

This map has some really great lighting effects. Unfortunately, it also has a bunch of rooms that give me a nasty headache. Worth downloading for the ideas alone.
