I can't promise a quick solution, but I'm liable to get round to it eventually. Version number and screenshots welcome.
Same issue, inventory just doesn't open at all, and moving to the next floor also breaks.
I built the Linux version on a version of Ubuntu that fits on a thumb drive. It wouldn't even run properly but others said it was okay. I've no idea how Linux stuff works so perhaps it's similar to a Mac app where it's a folder full of resources.
I can't even get Linux to work on any of my machines any more so I'm afraid I can't offer anything else. The executable did nothing other than run the swf in a wrapper. So if you can play the swf you're playing the game - the exe or app version isn't any better.
