Wow. Then I don't understand why it's in such a bad state.They actually did that. It was in beta for over a year and a half.
Anyway, this is way too unstable right now, I tried the tutorial but I encountered many more problems than during the demo, and it's not even possible to save the game. It's also very straining on the eyes because of the pixel art (pixel hunting for ammo and other stuff is a pain).
There are parts I really like, but there's too much inconvenience to make it bearable for long, I really hope it changes dramatically after a good debug session.
