Fun easy game, not much depth and is alright for a few times through. I suppose it fits your description, although it could've used music and a mute button at the same time. I wouldn't have minded the incessant popping sound if I had a nice loop of typical flash game music although with silence the popping sounds become quite annoying. Other than that it's pretty solid for simplicity's sake.

Gamebrew: I'd like to start a feature on "COCAK":http://www.cocak.blogspot.com that showcases a game of the month, I've chosen Tactics to start it off, and I was wondering if you would be able to provide a interview based on the development of the game, from concept to creation.
