Is the above the least useful screenshot on this site?

It is a useful screenshot... it's just displaying at the wrong ratio. I'll flag it up to be fixed, thanks. :)

Is this game available to download anywhere?

Yes, it's in the collection at the MZ-80A Secrets site... https://mz-80a.com/games/

@Strident: Thanks! I've never emulated MSX before. Do you have a quick and easy way to get a copy of the BASIC listing for the game, by any chance?

Er, ignore my previous comment. It was clearly gibberish!

The screenshot is interesting as there is a blue background! The MZ-80A didn't have colour (beyond its monochrome green screen). It suggests either the game was also released on the MZ-700 (I've not seen proof of this yet) or somebody has converted the listing to the MZ-700's S-BASIC (which is fairly easy to do as it automatically converts MZ-80A's BASIC tokens to S-BASIC tokens when you try and load an 80A program). I'll be posting my solution to this game shortly :)

Unlike the other early Kuma releases, the game seems to have disappeared quite quickly for Kuma's catalogue... or at least the magazine advertising. I wonder what was the reason for that? Licensing issues, perhaps?

It could be that! Perhaps it wasn't selling well. Alternatively, the spelling and grammar are pretty poor (and they've not even bothered to check whether a word is split between lines on the screen so it doesn't look particularly nice either - almost like it was a rush job).

@Sharpworks, do you know how to get the BASIC source code for this game?

Hopefully you're getting my messages on Twitter now. Let me know if it helps :)
