A fun puzzle game based on tower-defense strategies, it is a way to increase the difficulty of tower-defense games as GMTK always says in his video about TD games. The controls are rather strange in a way, but I quickly got used to it.
My mind isn't really tuned that well to strategy and puzzle games, but this is actually really fun and good if you get the right combination of defeating the little imps invading your home. A bit of polish would improve the game well, and give it a boost of potential.
