Dear creator,
Great game, had me addicted. Would have like somewhere to use xp, maybe a trade into other units for exceeding cost? It would be really nice to be able to upgrade mana as well, even just an extra 50 would have been nice, or a higher rate of return. Levels were really challenging, really enjoyed how it was a real challenge by the end, and it took some time in order to get anywhere. Well done.
Beat the game... used Queen Etheria the entire time, her healing helped the entire way through. Had trouble on Collossus, Beast King, Iron Fortress and Lone Blademaster. Ended up finding the easiest option: Beefy guys with lots of health and damage, associated boosts. Left the hero in back, no point in having them up front if you loose if they die...
Collossus: No need for freeze, just send a bunch of little guys at it, backing up your most powerful range troops when it starts getting to close. Put up arrow towers to stop it as well, aim to slow him down as much as possible.
Ragnarok is easy, just do it at the very end of the day, use holy grail and shoot like crazy with ranger or an HMG with good acuracy. i beat on day 17 and gained 6 lvls
