Yeah, WMP isn't the right program to run flash games (aka .swf, or known as Shockwave File/Flash); what you want is a flash player/projector, such as Abode's standalone. -- Though, it'll be discontinued soon.So Chapter 1 works just fine. But Chapter 2 and 3 are forever "buffering" when I try and open them. Does it have to do with using Windows Media Player, or am I glitching out?
If you don't want to download, you can find the game on newgrounds; though, I believe flash will no longer be supported soon, at least for Chrome (and for firefox, you'll need to download it anyways). -- IIRC the downloads here wasn't updated after the initial upload, so newgrounds is the better option.
