I would also like to know this, I got a new computer recently and lost a few files.
I'll probably download both versions if the original does become available again
We're honestly having quite a bit of difficulty porting from one to the other, as Renpy is a script-based engine (long python files) and Tyranobuilder is an engine that relies heavily on in-engine instruction (selecting individual images/audio files/etc.) but we're doing our best. Unsure when the original will be available, as the new one takes priority.
If you paid for the bonus edition, please send us a message once the new version is out and we'll be sure you get a key for the trouble.
