Good to hear. Didn't test the multiplayer because I'm friendless and don't have 4 hands, but it sounds like it could be neat, if a bit clusterfuckey.
No new demo this time, not sure if I'll do another one because adding stage 3 would mean more than half the game is in the demo, but we'll see in the coming months. I did update the dd16 build with rebindable controls and a JP translation (More news coming from that soon here...) if you didn't see that.
