The sweet sweet lore~
I love the cutscene at the beginning. Rat lore.
The style of the game has a very unique feel, and I love it. I do think that you could spend more time in the future on fine-tuning the gameplay, as it currently doesn't feel very concise. Each mutation feels... Odd. Controls switching during gameplay is also very odd. If you gave the player a heads-up, or streamlined the controls, I think it would be much more enjoyable.
