This is one of the most original concepts I have ever seen in a gamejam game, amazing work!
It has a bunch of classic issues for multiplayer games that could all be solved with more playtesting (balance, etc), but the core concept is really strong and I've never seen anything like this before, which really really impressed me.
I don't have a lot else to say, it played well, graphics were great, concept was exceptional. Great work!
