I highly recommend looking at the ceefax games archive on https://www.bbcmicro.co.uk/?search=Ceefax&on_P=on. Check out 'Harbor Command' for another(less sophisticated) first person game

That's different. This uses an infrared receiver on a Linux box to render out a teletext stream that's interpreted and displayed on a TV.

The CEEFAX games in the link on the other hand were games transmitted over CEEFAX to be loaded into a BBC Micro and played there.

Either of those things though is very cool.
