After playing several of the builds over the past few years, this game is REALLY bad at actually telling you how to play.
I only really knew how to do the main gameplay (which is now apparently a chapter 2) because that was the only thing present with the least changes in between builds, and because somebody in this comments section explained how to play about two years ago.
Having to rely on external information just to figure out how to play the game is very poor game design. Add in a proper tutorial (even if it is just the most bare-bones list of controls and things to pay attention to) because this just carries the same amount of confusing jank no matter how many times the entire thing is reworked every few months.
