Very nice game. As for a tower defense it doesn't experiment with anything new but set many already known stuff. Ground and flying units with their magical and physical defence. Stages are nicely designed and can be completed by a lot of different ways. Every single playable main character is unique it is possible to finish the game with playing only the favourite, if somebody like that idea.
Also for those who might be interested only in "story" offered by the game, everything (really everything) can be skipped, allowing players to get to the point they want very quickly.

If I shall point, the major flaw of the game would be the very simple system of upgrades, with just few upgrades for each character and building. No talent-tree, no choices. Just upgrades. The game is great, but it's there.
