Fun, but it has a few weak spots
Ok, it's fun to send your comically large swarm of troops into battle. But I mean, if you play it right at the beginning, it becomes way, way too easy. I'm on level 47, and I can annihilate the other castle with less than 30 units. The secret is in the upgrades. I spent about half my money on unit upgrades every level (the same units, mind you), and now I can raise a castle with like 20 archers.
It's crazy fun, but I would like it if the castle you fought got a little more advanced...you know, catapults, a moat, etc. I would also like a way to see how many of each upgrade you have. Thanks! Great game!!!!!! I love it!
