Well I got "not a valid win32 application" :/
Is there any way this can be made to run on XP ?
Unfortunately, NW.js which is used to run the game has dropped XP support. However, if you go into the package.nw folder and open up index.html in a modern browser - Chrome should work perfectly - then you should be able to play.
Sorry about that, let me know if you're having any more troubles.
(I just checked in Firefox and it's playable, the pog betting slider isn't formatted correctly but it's playable, this almost certainly won't work in IE)
