Tower of Dreams by SuperCitrus is a game made for the Nintendo Game Boy.
Your goal is to climb your way to the top of the tower. Bound off walls and make use of Dream Knight’s sword to bounce off obstacles. As the author says, ‘The game is currently in early development so what you see here is a very short demo/tutorial of the art, mechanics, and physics. My goal with Tower of Dreams is to make something with lots of depth and skill that’s accessible to as many people as possible, which is why the whole game uses just one button.’
