ahhh i love games like this! have you heard of hypnospace outlaw? it's honestly really fun and interesting and reminds me of her story in some of its design.
i think there's a couple tutorials on ren'py forums for point and click stuff but im not sure theyre much more descriptive--and it's honestly really brave of you to list out some features that you think would be cool even if you don't know if you can get them to work. i think this will be fun because you might find some features might work but you have a lot of fun features to work with so i'm sure you'll learn a lot. i'm really interested in seeing what you can learn in the two weeks!
