You know how it is with perfectionism.. With the unlucky surprises and issues with the engine (godot is amazing, but being an early adopter of v4 had its risks of course) that were discovered in the later stage of putting the stuff together, we weren't successful in having something more tangible. In fact, our scope was cut several times throughout development. And yeah, the run up and present progress make it quite tempting to continue with the project, at least for me (the fish-hook, programmer).
And yeah, thanks a lot for the review, we read it much sooner than we replied. I guess it is the perfectionism that postponed a reply.
