I love a game that forces you to have to make a choice between spending workers/resources on defending, or on giving yourself a larger amount of workers/resources so your defenses can be stronger later. A very casual game that never really needs you to click around too much.
My only wish would be i would like a few more faster time speed-ups, as some early waves can drag.

For the price this is one of the most fun tower defense games I have played recently. I would pay for it again if that means I would just get more towers, more upgrades and more bonus tiles on a bigger map, but even as it is now, it's a very fun little game.
