I was very skeptical about picking this one up as I have not had much good experiences with gesture controlled games. I was pleasantly surprised to find a great deal of fun and replayability here. You are going to get destroyed if you think you can just "flick" your way out in this game; you have a limited ammo supply (in the form of a mana regen bar) so you better make your moves worth it. Among the spells you can cast theres a thunder (that hits nearby enemies if landed succesfully), fireball (damage over time and large Area of Effect), Ice block (shield blocks that can block a path to buy you time, very important for regenerating your mana). The spells, along with your regen rate, and defenses are upgradable and I can imagine myself trying different upgrades in each game. At this price it is a stealer. I am not a big fan of castle defense games at all, this really is different and has tons of replay value. It is quick and fun quick like minigore but a lot more depth and value. And more polished in my opinion.
