There would have been a better challenge if there was a way to lose.

yeah ..technically if you don't send anything .. you can lose x) (on wave 10 if the castle survives you lose)
but the balancing sadly is way off.. and i didnt have enough time to implement the planned settings menu (or even a config file for that matter) to be able to tweak things on the fly. im happy enough to have the core gameplay loop and a game submitted without crashing or major bugs tho.
thanks for the feedback :)
