I did release a Windows 32 bits version shortly after your comment (sorry for not responding until now), along with a OSX and Linux build. The stats so far show that these builds are downloaded roughly 10% of the time compared to the Windows 64 bits version. Considering these downloads come most likely from people actively searching for them, that's not a whole lot. It's also worth noting that I don't currently have a way to test the 32 bits and OSX builds, so I can't officially support them.
Realistically, I'm afraid I'll only be able to offer the Windows 64 bits version in the foreseeable future.
