Ill start with the cons. Its the shorter list.
1. The final level is not the exercise in futility I was expecting. In fact, it can be beaten in under a minute on hard. Make it harder!
2. Limited replay value. Ive beaten the game on medium, and most levels on hard (34 will be the most interesting), so what now? Level packs would be awesome, and I would pay money for them.
That said, this game was worth the money. Creative levels require a strategic mindset, particularly on the later levels. Level progression is logical. The AI is the most annoying thing to cope with on hard (this is a pro). Very good graphics and music. Overall a phenomenal game!
