Addictive and fun. A few flaws

Absolutely addictive. Levels are extremely hard and I like that. Very fun.

Problems:
Sound is intermittent. Sometimes it is muted and other times it is fine. If your phone rings, after the call, the game will be silent. You have to close the game completely and relaunch to get the sound back.

Lasers - I cant get them to lock and unlock their aim. I try to double tap but it doesnt lock its position.

Problems aside, it is my current favorite tower defense game.
