Thanks thanks thanks and yes yes yes :D
I had so much already in there. Obstacles. Asymmetric level design. Physics based push back on hit. But it all broke the game design :D
What I really really enjoyed about this prototype is that its always "either multiplayer or AI", and this was more a "you vs. you + AI" (aka. joined together indeed :) So if I can make the AI and level design more fun, less exploitable, and actually have a skill curve, this would make me insanely proud and happy.
Thanks again for your help and compliment on the presentation!
