Please make a Linux version. Your software is already free and open-source. The last step is to make it available to a free and open-source OS. As hackaholic5069 and Gustavo H M Silva already mentioned, you could just use a virtual machine and compile from there.
Gustavo H M Silva seems ready to help. I suspect you will get more and more people asking for Linux after they watch Gamefromscratch's video about your software. Brace yourself ;PP
