This game was pretty difficult but rewarding. It was entered in the La Petite Morte part of Ectocomp, which is surprising given its complexity.
In it, you have a large rectangular grid of a dungeon, and you have to make a map for adventurers to wander in. You have to destroy adventurers, but to reach the weapons you need to hit them, you have to make a path that adventurers can also take, and if they get the weapons, they win.
I was baffled at first, and had no clue what I was doing. I found that the adventurers follow close behind you and can kill you the instant they have line of sight. I also found that you can't throw the killing weapon unless you have line of sight.
So I was truly baffled until I read the hints on the Psionic weapon, and then things became a lot more clear.
Overall, this was pretty fun. My only sticking point was how hard it was to get started, but after that I liked the puzzle.
