Amazing
This is the best tower defence game I have ever played (partly because I actually had a chance of winning this one). Sure, it's got a few bugs and some stuff doesn't really make sense, but the spirit of it is perfect. It really inspires creativity and you really have to combine your traps in a more complex way than just putting strong cannons at corners right after some ice towers. Watching a bunch of little pirates getting pushed around by logs gives a real sense of satisfaction.
Keep it up!
