Pretty weak, very repetitive. should balance it to require less units (stronger) but cost more resource. Also units shouldn't die in one hit. Adding an upgrade system to the whole team after each wave could be good customization. Such as, pick one-5% more attack speed 5% more range 5% more resource.
Controls are really infuriating. Characters slide off blocks too much, and jumping back and forth in small confined areas you tend to hit the roof and not jump at all so you get stuck. 3/5
Units that are slammed into a planet through gravity should take some "falling damage" Also, make poison dart and clusterbomb a bit better, maybe throwing mines rather than just placing.
Terrible card system, hard difficulties cripple you too much for a luck based game. Some of the castles start off with over 30 of one resource and they can dragon, comet, pixie, babylon on the first turn giving them too much advantage. 75 card minimum is stupid, 5 cards of each is stupid, really really bad game compared to the first. 1/5
