This is quite possibly the most aggravating game I ever played. Perhaps it's because I use a touchpad to play, or perhaps it's because of the screeching killscreen that rips out my eardrums.
An excellent game with all the qualities one can appreciate in a TD game. I have no idea how to stop the phantoms from reaching my gems before I manage to kill them. They're a real problem, and I can never get more than "excellent" on paths with two entrances because of them.
