Chronosoft have launched a game on cassette for 16K-expanded ZX81 owners: Tut-Tut, a puzzle-arcade game based around the excavation of Egypt’s pyramids.
Tut-tut was written by David Stephenson and is a conversion from his ZX Spectrum original. Both versions of the game are available digitally as a download from his website.
The cassette version can be acquired from Chronosoft here.
