I do not feel like the towers scale with the monster difficulty. The early game is a blast, but the exponential curve later on becomes discouraging, even after dropping some money to power level some items. I wouldn't recommend spending a dime until it's actually worth it. Great game for the first 15 levels or so.
By far one of the best games I've played on Kongregate. Worth paying some creds for the whole thing. Great story, silly dialogue, fun gameplay. 5 stars.
