Sorry there hasn't been much of an update. There's not a lot I can say really other than I'm attempting to get started back up with Dinosaur Resurrection.
As far as Zwei!! and Zwei 2 go, they're not abandoned projects, but....there's nothing I can really say about them at this time.
If I haven't heard back from the programmer I'm working with on Dinosaur in a couple weeks, I might open up a suggestion box for translations for people though!
