To be clear though, I think everything I say above would be inappropriate in tech-themed games like Artificial Nexus (Or Coffeedrip Studio's Esper X Guide.) where the whole theme is that you're battling against an indifferent computer system. In those cases, it's thematically consistent that the player's entries are somewhat colder.
I'm also aware of examples in Noir where a serious decision 'pops up' in a way that feels inappropriately cheerful!!! Argh!
I suppose that all I mean by the post is that this whole area of screens entering/ leaving in RenPy is a design space that I really appreciate seeing people play with (Although I admit I might be crazy.)
