Idk your visual novel preferences but here are a couple that i think are cool:
Who Is Mike is a pretty short VN, but it has 9 endings. You can get it for free on Steam/itchio
The Silver Case is way longer and there’s no choices in it, but I still found the story enthralling. It’s like $5.99 but you can check out the demo for free on Steam or GOG to see if you like it.
