Doki Doki Literature Club is a free game (there's a paid version but it's not on itch.io and I didn't play that version yet) and it's very scary. It was a part of my inspiration to start using Ren'Py, as well as my cousin using it. My cousin's games are also on here. NOTE FOR MODERATORS: No one told me to put that link there, and I didn't help with any games (yet, because we're planning on collaborating.) I'm recommending these games because they are awesome, and... Okay, that's all lol.
