You can download the Gallery's games and play them on your own computer.
Source code
Choose this if you want to build the games yourself, or investigate how they work.
Linux
Packages may appear someday.
Mac OS X
These are unsigned, so your computer may complain about running untrusted programs. I'll fix this if someone sends me a free MacBook and $100 for an Apple Developer account.
This build is also a few years old. It doesn't include Advanced Rogue 7, XRogue, or recent bug fixes. Sorry.
Windows
I'm hoping to have a Windows 8 build ready by the end of 2015.
Bugs?
