Yes, there isn't much explaining yet.
When opening up the menu, the controls are explained, but not on what to excately do...
I can add that in the last step. The game is a bit UI heavy, meaning a load of UI parts, which doesn't leave room for text. I maybe have to redo some parts.
I think I changing to show the controls per phase in the menu that would leave room for general instructions.
In general much more visual feedback would be great. So the kife could change color when in the right spot.
