Yep! KKairos was being a bit optimistic, but hopefully only a bit--we're going to try again tomorrow with a Linux build for the final jam version 0.99!
Aight. That's good, because we're running into more problems than anticipated. I know this is possible because I did it once, but it might be a day or two. Thanks in advance for your patience!
Strange. Slackware64 14.2 on the computer I used. It has a 15 year old CPU. This might be one of the somewhat uncommon instances where Wine itself is at fault.
