You should package it into a zip file and than upload it, I had the same problem a few weeks ago, it is quite hard to understand the first time arround. Just archive it as a zip rather than a rar and than set it as play in the browser :)
Thank you! It's working now.
Yup, just played it, it is a really good experience ^^, it really has an original plot and I liked it, well done!
