Name Pun: demode ("dated" in Turkish), d-mode, (and may be) destruction mode :)
It's a rather clumsy, cliché-filled and I think, unnecessarily difficult game. Still, it is a work that I spent a lot of time on and enjoyed while design and coding.
When I coded it I compiled it with Turbo C on a PII 233 pc. It must be DOS or Windows 95, I'm not sure. Nowadays, to do the same thing you will probably need either a non-64 bit operating system or a virtual machine with old DOS/Windows installed. I can even say that the same conditions are required to play, it is such a historical development.
