This is what I used to achieve the pixelated style. It's kind of a hack, and it basically takes the scene, renders it onto a texture, down-scale it, and have another camera look at the down-scaled texture. It probably should be some kind of post processing effect instead. Wouldn't recommend outside of a game jam.
But yeah, thanks for checking out the game and for leaving such a kind comment :)
