You made a siege game too? I'll HAVE to check that one out!
Thank you for playing, sounds like there's plenty of parts you enjoyed/liked and that is great news. I'm glad you enjoyed it. As for the feedback balancing is priority number one in any future update, its the most mentioned comment I've received. But I am glad you went into more detail about it, the knight archer combo killed me a lot too. I'll be sure to lower the unit costs in version 2.0.
Returning units is an interesting idea to recoup some of the unit cost too. Maybe you just click on them and they retreat. I might use that, thanks for the idea!
