Despite the few issues with the performance which some people already have commented, its a pretty interesting game. I liked the art in general, but some things still need a little work. Some unities were really useless, compared to the price you had to pay for them, like the Dragon. I was expecting some major fire damage to the enemies but it took me years to level it up (once) and I still didn't understand the point of the Corpse. Couldn't see if it gave damage at all to the enemies, the Hive is something else that personally I didn't like. If it's a hive, it should have more than 1 bee attacking (bees don't attack alone), the number of bees could be upgraded. Also, after some point when you can have your unities destroyed, we should be able to buy new upgraded ones, the upgrades could be unlocked, it's really unfair when you get to the last wave with all your unities fully upgraded then destroyed and all you can buy is Lv 1 Skeletons. About the performance, even with the lowest quality it got buggy, and sometimes it's impossible to level up the unities because of the lag, not mentioning impossible to use spells, what costed me a couple lives. One last thing that I think that needs a little re-check is the Hiker. It starts climbing the walls randomly, but its kinda unfair because it comes from behind the Evil Queen or whatever, and I have no unities there, all we can use is spells, but if its laggy at this point, it becomes an impossible task. Maybe some defence spells for her or some extra protection.
