A quite substantial patch of the demo:
- The tutorial is much larger now, with four opportunities for players to try out the core mechanics.
- The level history has been revised such that players might actually have a chance to understand what's going on.
- Red rods are brighter now when they are selected; blue rods are brighter now when the player is hovering over them.
- New keys for canceling: tab and backspace; new buttons for horizontal movement: bumpers of Xbox controllers; new buttons for vertical movement: X and Y buttons of Xbox controllers.
PS: After uploading, I found a tiny problem in the new tutorial (the graying of rods is not deactivated again when you go back over the point where it is activated). This will be fixed in the next patch.
