CREATE INTRICATE MACHINING
Traps are full of hidden secrets and interactions. Learn how they work and exploit your knowledge to deal maximum damage.

LEARN THE ENEMY
The enemy is well prepared and has ways to counter your defenses. If you learn them, you may be able to counter their counter.

ROGUELIKE ELEMENTS
Explore procedurally-generated environments and defend them all – every arena has its own interactions and emphasizes certain strategies over others. Maybe you can even make the arena dispose of some enemies for you...
WATCH THE BUDGET
Building traps takes gold, and the gold you have must be enough to defend several arenas – you need to watch how much you spend, or there won't be enough left for the next room.
BUILDING IS THE FUN
Get in, build your defenses, watch a bit of suffering, and get out. The fun is building devious contraptions, and that's what you'll be doing the most.
