Where did you get this from?
Looks like it is built on the open-source Wolfenstein engine from
the Carmack that ran on my 80286-based machine with 2 MB of SDRAM.
Since computers are powerful and cheap nowadays I will base my next game on the excellent almost photorealistically immersive Doom engine (by the same
the Carmack), which ran really smoothly on my 80486 DX4/100 with 8 MB of SDRAM. It was bought in 1994 for $1200, and now a computer of even a greater power can be bought for as little as $300, which ensures that my game will be popular even with users of slower machines. Both engines are FOSS.
