I know this is a demo. But, I'm going to be honest. It's a disappointment. The controls are inversed. Plus, there's no clear instruction on how to interact with items! What do I mean by inversed control? The character turns right when I press left. Was there any reason for making the control so complicated?

This game uses tank controls. Due to the way the camera angles change while moving around in the world, this control scheme allows for the best way to maintain the same direction during a camera transition.
Think of it like this- your movement is based on which way Haneko is facing in the game. "Left" to her is not the same "left" for you, so when you want to go left, you have to assume it from her perspective.
