It was a lot of fun and turned out to be a very good tower defense game. The graphics look good and there are lots of features built in to keep the game from becoming monotonous.
I think there are too many resources for this game (if it were bigger, it would probably make more sense).
And unfortunately, I didn't think the theme was quite right for the jam theme. (Maybe I didn't understand it :D ) But I definitely had fun and it turned out really nice :)
