Most tile based 2D games are pretty boring and generally incredibly badly designed, either in terms of the level design or the game play itself. But this is a nice surprise, and the game levels up very cleverly. In that respect, it reminds me a bit like Plants vs. Zombies in the way you get hooked on game play and don't want to put it down. It's well balanced and easy on the eyes and I think it will reach a very broad audience, from 10 to 80, and that's no easy feat! I've seen in several forums some (understandable) player hysteria because they are stuck on a level and can't find a walkthrough. For a game that has about 100 levels this can be a problem but these designers have thought of everything! For the walkthrough, just look on the opening first screen where you click Play. There is a "Solutions" button that takes you to a screen shot of whatever level you are currently on with the solution! This fun game is an instant classic.
