I very much enjoyed, the art was great and I digged the black and white of the first couple levels. The gravity falls bit broke my immersion a little but the game design throughout was very good. Could really have done with audio, but you know that already because its absence is a bug. Chapter 2 was my favourite, swapping platforms isn't a new mechanic by any means, but I really liked having to actually think ahead with them, and you innovated on the idea in the level design in a way that I found very novel and cool. Overall you did a very good job.
