I believe the scene viewer mod covers all that, thats why I did not dive into it. As my mod is more about gameplay, not just seeing the scene. But I totally agree with you on the game engine aspect. It is a great limitation and mainly used by those who don't know programming or just want something quick quick. I preferably like Unity, renpy is okay just not a big fan of it. But there are so many game engines out there I love. To me, this engine is not even in the category of low tier, it is far lower. Not complaining, just when you can code, you can do far superior stuff and not dependent on plugins or drag and drop crap.
Im not bashing the game, the dev has done wonders with this engine; just to me, it reached its max push and is noticeable.
I just talking about game engine in general and hope MNL 2 is on Unity
