I got to play the Renpy version for the first time and I'm really impressed! Everything is an improvement with respect to the other version, and it works seamlessly. Only thing, the sound effect of when you put things into the inventory is a bit weird, and rather unpleasant.
Ah, and I'd add the Load button and the Main menu button in the string of commands at the bottom, currently there's just the Quick load (in addition to save and quick save, of course).
I know that in Renpy it's possible to name the save slots (useful if, like me, someone wants to pursue multiple routes). I don't seem to have found a way in the current version, is that implemented?
