I'm totally fine waiting for an update. But since it's been a while, replaying the game without much change might be fun on its own. Guess it depends on how much longer it would be for the next content update, and how much work getting a demo ready would take. It it'll be a while, then having something to play now would be nice, unless it delays that update too greatly... Feedback is important though, so in that sense getting a demo out is important... IDK!
P.s. Distortion is fun :3
