I need to play this with someone to get more depth but I'll leave my thoughts of testing it by myself.
I think this is a really cool idea! I never thought you could do a 1 v 1 RTS on the same computer but using the theme of the jam you managed to do that. As I said, I need to play with someone in order to see if there is any exploit out there, but seems good on that aspect right now.

There is an sploit. In one line of code I wrote red instead of blue and made the blue castle harm the blue player instead of the red one when the red soldier attacks it. So red attacks with a soldier from a side of the castle, he will win 100%
I'll have to wait until the Jam ends to update the game. I'll also have to fix a couple collisions.
