Above is the brief (in Google Docs which has changed some of the formatting). I liked my ideas and how they all had a reason behind them, however, brief 1 wasn't liked and that was going to be my major one, whilst the steam punk animals were going to be ornaments for a level. As brief 1 wasn't liked I now feel this module isn't going the way I want it to.
So I'm going to change the brief completely so that I actually like it, which seems a bit extreme but will go in the direction I want. I'm going to email Phil to see if this is alright, and then post what I'm going to do later.
