Tiny Heroes

[UnSub]

A Dungeon Keeper-esque / tower defence title. F2P with some cash shop items, but early on if you aim at getting the extra defences from the achievements you won't need it.

I've found that the difficulty level ramps up relatively quickly and it is very easy to get overrun (especially with epic knights) so it's a case of trial and error plus luck in passing some levels.

It's also a bit touchy on the iPhone screen - I often find I'm putting my defence piece one space to the right of where I want to due to a last second slip. So it may be my fault, but I haven't found that happen in other titles I've tried.

That said, it's worth a shot if you feel like slaughtering heroes with wall blades in a dungeon.
