Watch the mouse's drop shadow to know where he/she is standing on the ground.
The buttons, (don't click) just move the character over the button to activate it. The buttons with "⻔"
will open a door and you can move your character over the door opening to enter.
Watch out for the electric walls and enemies! If your character touches them, they will instantly kill
him/her. The blinking wall part is the area you can’t touch and your character's drop shadow is what
can't come in contact with it.
