Thank you vey much for the suggestion :) I'll incorporate teh feature as I have the counter already.
As for the likeness of other ZX81 games. I'm quite new to the ZX81 - I only recently acquired one, so I practically haven't played any games on it. But I think you have a good point.
Personally I wanted to challenge myself to make something in Z80, so I found an excellent tutorial from Dr. Beep, that taught me how to read input, make timers, manage the displayfile etc. I made this game as a tribute to Dr. Beep and his tutorial - but I might suspect, that other have been inspired by the same tutorial also :)
