Initially it was a bit difficult to grasp but on my second try I reached Wave 39, with 264 health! xD Would like to see some sound effects. Perhaps the way we are adding armour and providing weapons can be improved. Instead of clicking and dragging to slots, if we could drag and drop weapon/armous sprites to the required places on the actual soldier, it would seem more like I'm actually "building" the offence/defense. Nice concept though.
