Hi there,
I set up a script to compile the Windows version every night using the latest source code from GitHub.
As I am certainly not the only one wanting to check out the newest version every now and then, I decided to make them publicly available here:
http://grigro.bplaced.net/catadda-win32.zip
I also compile a 32-Bit Linux version, available here: http://grigro.bplaced.net/catadda-linux32.zip
They should be updated each night at around 5am (UTC +1 or +2, depending on daylight saving time).
Have fun!
PS: Should/Can I add this to the wiki?
EDIT:
Please be advised, that there is no guaranteed save game compatibility, so each version can break your existing world. Best way around this is to extract the new version into a different folder and just copy your existing save folder. This way you lose nothing should something go wrong.
