Ok, I actually had to pause this game to get around to writing this–the game is that much fun. It’s similar to a lot of other Tower Defense type games, but with a twist (naturally). The towers aren’t initially active; to make them do anything, you need to drop a gem into it, whereupon it starts decimating the almost undending stream of monsters that crawl along the path. You can cast a small number of spells that affect the gems and the gameplay, and you’ll find yourself coming back to the game if only to see if you can open the hidden stages. Ok, that seems to fulfill the demands of a post–I’m going back to the game now.
