Hi Ameena. I finally got around to reading this!
It's a reasonable start, but I'm sorry to say that it hasn't grabbed my interest. In another thread, Beowuuf complained that you spend too long explaining the mechanics of the game and I agree completely. Some of the mechanics of the game are actually pretty silly in real-world terms and to try and rationalise them into a real story I think is pointless.
I am much more interested in characters and atmosphere. I think you've started to develop the characters quite well but on the atmosphere stakes it does not feel like they are in an oppresive dungeon. I would recommend that you change a lot of the exposition about mechanics into more atmospheric background and better character interaction. It seems like all the characters instantly get on with each other, and although you've tried to explain this by having Theron's voice explain their mission, it's not really explored very well. I think there would be much more uncertainty, confusion and distrust when they all initially meet. I realise you've only just started, but I hope you introduce some conflicts and upsets between characters -- so far it seems they are all best buddies. And a small point - the names seem a bit trite really and I have difficulty not laughing at 'Fippy'

Anyway, it's your story at the end of the day, and you must always write to please yourself, not others, so I'd be interested to see how this develops.
