The game is pretty straight forward and it isn't that long.Hey can anyone give me a full save?
You can't really make the wrong choices as you have rollback if you choose a "game over" scenario. If you have bought something in the store and you can't find a way to use it it's because it's not yet in the story. For example you have been able to buy all 3 dresses for the longest time and you still can't use all 3. Which is bad design as people will think they have done something wrong.
