in general, if we are serious about version numbering, then this version is never 3.40. it's still the same 3.20 ... or rather 3.20.1 - that is, it is nothing more than a technical update.
based on, for example, the game "no man sky", where they changed the engine from the one that works through open-gl to a newer one with support (I forgot the word, it starts with V, Vertex, maybe) - well, the engine change was accompanied by a content update. Many new features have been added to the game.
and here? It's just a change of engine. new content - zero!
so, sorry, author, but you have no right to increase the version number, this is NOT 3.40. author, you misled us.
or maybe the author did a feint with his ears and added content somewhere in the middle of an already existing script, for example, added or changed some scenes? for example, the creator of VN "hot springs academy" did this - not a completely honest step, but in fact - in fact he ADDED new content, and I cannot deny this. he had the new version right.
and here? What content has been added EXCEPT for the actual replacement of the engine?
