Wow another Pinna-enjoyer! There are dozens of us! I hadn't heard of it until a couple of years ago but recently got into it. It's on the list to review soon, but I may try your version and link to it if you don't mind. The first time I booted it up an included save game on my version it spent ages counting to what I assume was 30 years, day by day, until it finally showed me some dead birds. It was excellent.
