The 1989 PC MS-DOS conversion of Taito‘s classic arcade game Qix was programmed by the Alien Technology Group and is excruciatingly difficult. At least: that’s what I found.
I love Qix and wanted to make some headway in this but couldn’t make it past the second screen. I don’t know why that is. Maybe it’s because I’m sh*t? I don’t know.
Otherwise this is a very good conversion.
