I haven't played the game, it looks alright, if it wasn't designed to milk your money I'd get it. This is just a side note but I just read Rovio's Wikipedia article and they've released 11 games in the span of 4 years. That's pretty sickening, and it shows the causal game market is treading on very thin ice.
