Thank you very much for your reply. I realise that converting Rastan is a huge job - and that you have already done an enormous amount of work on the first two levels. So I really don't want to put more pressure on you!
No doubt, lots of people besides myself are asking you to make changes: add stuff, take away stuff etc. This may not be as helpful as we intend!
Personally, I think you are the one best placed to judge what to leave in and take out. I advise taking all suggestions with a pinch of salt - including my suggestions!
Thanks again for all the effort, skill and talent you've put in to this. Back in the day, I always wanted an Amiga version of Rastan. And it's finally arrived! The version you've created was definitely worth waiting for.
