Thanks for trying! Unfortunately it's extremely old and I'm unsure on how well it works on modern PCs. I do actually have a development version that's remade in 3D, but I haven't had time to work on anything since having a full-time job.
Ah ok, happens with old software I guess. I was specifically drawn to it as I recently started developing my my first X-Com-like prototype and was looking for some inspiration to get me going. But now I'm in a similar situation as yours, trying to find the time to work on it. Hope you can find the way to be making cool stuff again eventually.
