A somewhat weird RPG that revolves around setting traps [on a grid] that deal damage to enemies who follow you around the dungeon.
"With the devil by your side," the game's description reads, "play as princess Allura, as you lure your enemies into your intricate web of traps and dark illusions. All in the name of protecting justice and saving your kingdom. You will plant a series of deadly traps that will main, burn, behead, and consume your enemies' lives, leaving their souls for the devil."
Tecmo created this, so expect a lot of beautiful anime girls and fan service.
