the only advice ill give, is that you should put the instructions in the game, and avoid using phrases like 'kind of really hard' and 'able to fire fire'. As well, you should avoid using material from another person's work in your own unless you either openly acknowledge it is theirs, or you are creating a fan-base type of work. If you refine it a bit, add a non- linear plot, and change the font, this could be a great game.
left 4 dead and this game are not even close to reality, although they are both entertaining. it is interesting how most of the questions are just trial and error. the only way to really know which option is best is to understand how the author thinks.
