First off, love the project. I have it running on linux and am so glad I can put all the data in one directory except the config. That way I can back things up properly and install on any system. Never used an appimage before old to unix and linux but away from it for 20 years but it is a fantastic way to do things.
Is it possible to have HD sprites?
I get no sound in the intro is the problem my data or is that normal? Is there a specific file to check? I have a bunch of versions of xcom so maybe this one is bad?
Also, my eyes are good enough to drive without glasses still but I have a lot of trouble seeing this text, adjusting the default colors on the forums would be nice because I am sure I am not the only one.
