Thanks for playing!. I've posted a comment on your video with some of my feedback for it. Means alot that you've enjoyed and played it.
Yes we have alot of plans for a bigger game. We've released a new demo with better content but it's still along way from a full game.
Thanks :). No its singleplayer but if it did well we could try multiplayer.
Checkout the new demo we've improved the control alot!
