Everyone praises the voice acting, and I don't disagree; it's great.
I think this game captures the feeling of having several plates spinning at once fairly well. However, I also agree that the number of tourists to keep track of and how far you had to go away from them at times to collect resources made the gameplay a little tough. Perhaps the game would have been more manageable with a wider camera, or a mini-map (although that may defeat the point)?
I'm also not sure why there's a sprint button, as there isn't really any reason you'd ever want not to sprint. As is, it's just something which you hold down the whole time.
Of course, all these are footnotes; you made a pretty fun game. I'm impressed by the level of polish - nice job!!
