While you can make renpy do those things if you bend and twist it, this game does not look like renpy. And at 13 MB the demo of this game sure is not renpy. The options file in the demo makes me believe, this is c++ with libraries or something and not one of the common game engines.
The benefits of renpy are qol like roll back and save games. And configuration for text speed, auto play, skip already read text and so on.
A non exhaustive list of engines is here https://itch.io/game-development/engines

And many games do not tell in the metainfo what engine they use.
