Pros: Intriguing take on a good genre. Appealing graphics.
Cons: Much too easy and linear (once you figure out an effective strategy, you can just stick with it without even thinking). Much too short (you never get a chance to really upgrade much). Buggy (particularly the teleporting to the other side of the hall thing). Laggy at higher levels. One main component becomes useless rapidly (the main guy).
Great game concept, but poor implementation of the levels themselves. It is way too easy to circumvent the goal of the level (e.g., on level 28 just shoot the ball over the top and let it roll in to the bucket). With better attention to level design, this would be a great game.
Man, 58 is freaking TOUGH. Particularly since the slow time effect doesn't kick in easily... I'm clicking like mad, and it usually doesn't work for 1-2 seconds.
Seems to be a major problem with the towers. Put some up close to an opponents nest, then if that nest changes hands twice, you lose your towers, even though you created them from another nest that never changed hands.
