This is one of my favourite Boulder Dash inspired games. Great fun, and extremely playable.
A downloadable game
16K ZX81 - 2011
Bradford Walker-Smythe needs to find the perfect engagement ring to win the heart of his true love Tania when he asks for her hand in marriage. And so, to prove his devotion, he sets off to the Cornish mines in search of the perfect diamond...
Another kind of game I haven't written before. All of the examples I'd previous seen for the Zeddy didn't look very impressive - all single-screen with single-character graphics - and so I felt now was a good time to try and write a better looking and more playable version, with larger graphics and a fully-scrolling playing field. I'm also quite proud of having managed to fit 32 levels into the final game, which could possibly be a record on a 16K machine.
OldSchool Gaming - "...this is a great implementation of First Star's classic Atari 400/800 game Boulder Dash, and with 32 levels is probably the biggest game ever on the monochrome Sinclair... In my opinion, this is the best ZX81 game ever, just beating Bob Smith's Virus by the finest of margins. Taking the limitations of the hardware out of the equation, Boulder Logic is still a very, very good game" - 9/10
RetroGamer - Sizzler - "Boulder Logic is Bob Smith's attempt at cramming the challenge of Atari 8-bit classic Boulder Dash into 16K of ZX81, and it is admirable... The difficulty has been pitched well too, challenging players from the start and letting them discover the means to get through each stage..." - 90%
