A screen grab of the Amstrad CPC version
This long clip features some of the tape-loading sequence, if you're into that kind of thing! The Speccy game looks really decent and the 3D isometric graphics must have proved challenging to program on the machine. You will note that only one colour is used for each room, with all of the characters also changing to the same colour. Nonetheless, the game received 9/10 from Your Sinclair magazine in June 1987, with Crash! awarding 97%.
Here is an interesting walkthrough of the Commodore 64 version which features unrehearsed commentary by the video uploader Steve Benway. He is playing the game for the first time so he is quite bad at it, but this makes it interesting to watch, and it reminds me of when I first played the game back in the eighties!
