Very cool game :D I loved the concept of using your speed to move around. The soundtrack is also super nice. Was it also done by you? By the way, which engine is that?
The sounds were created by a friend of mine over the course of half an hour. I'll see how he wants to be credited on here (not sure if I should drop his government name). And as for the engine, this is done in vanilla javascript, using the HTML5 canvas.
