All fair points. As far as DOS games go, I wouldn’t say Jill compares favourably to Prince Of Persia or Another World either, both of which were released prior to this and also essentially developed by one person. As for shareware, I think the Keen series offered better gameplay with the smoother character movement being a major factor. The block based movement might be my biggest issue with JOTJ actually, it makes the jumps too easy to judge. I’m no doubt being ungenerous but I don’t see JOTJ justifying the $30 price tag given how brief the experience was. It’s an achievement having created it absolutely but arguably not the best value for money as a consumer.
I’d be curious to know if any of us Europeans ever actually bought full versions of anything shareware like this back in the 90’s. Without Paypal, I presume that to register JOTJ I’d have had to post a US$ foreign currency cheque off to Tim Sweeney in the USA, then pay airmail postage + customs fees to get it back again. That process would have cost as much as the game itself if so.
