Too much IAP required – Star Defense Mission! Review

Ive spent a bunch of money on IAP and put a ton of hours in, yet i still can't get past map 34 much less get more then 1 star on normal difficult in hardly any maps after 20 ish. Base levels take way too much grinding and the 2 skill points are near worthless once you max the tech trees. Fun game, but unbeatable on normal even with IAP. I guess if you invest a large sum of money in one use items it may be possible to beat each level just with nukes and stuff, but thats not fun.
