You're off to a good start!
The gameplay itself is simple, but I imagine it'll get more complicated as the game progresses. And even if it doesn't, I appreciate all of the bound hunks enough to keep going. I hope there might be some opportunity for choice in how to deal with them or the goblins, later down the line?
I think a little bit more guidance on things like the gun/bullet system would be helpful. It wasn't entirely clear what was happening until I got my first game over. But that's really my only complaint for the moment.
This demo definitely left me wanting more, I'm looking forward to updates!
