I love the premise and many of the options for choices you are giving. I think many would like to explore virtual reality worlds but cannot afford the technology to get close to the level of your imagination. With some of the options you are suggesting, I am unsure that the current V.R. technology could do it and that is what makes yours an interesting piece of interactive science fiction. Of course, I have not done very current research, so I could be wrong. Anyway, nice work on the speculative fiction aspects.
Next, I do think that those involved with “The Monkees” might take issue with the usage of “Daydream Believer” for a title, though your game has a far different context than the original song. You could do a parody title, which is protected by copy-right such as “Daydreamer Achiever,” for example. “The Dreams We Share” has a nice ring to it like the supernatural book and film “What Dreams May Come,” albeit, again, with a far different context.
By the way, when I did the plain vanilla skin option and then selected confirm, I found a bug. I think something was not placed into a variable at that point, but I do not remember the exact error.
All the best!
