Well well well, now that's interesting. I actually quite enjoyed this game, and even there weren't any colours at all, I still liked the art style.
The "sound thing" was a little bit better than in the previous games, but I would maybe pick different tracks and maybe add a sound effect when you select an action.
Anyways, that's pretty mcúch it. I'm going to participate on this "colour me" vlog, I'm already excited! :D
