does the game have actual nudity?
and where do I find Didnapper 1?
As the game description says, the base game does not contain any nudity or sexually explicit scenes. However, there are people who are working on nude and other explicit mods on our Discord server, and a basic vibe mod comes with the game as an example mod.
As for Didnapper 1, it's free and you can find it on the Didnapper Wiki: https://didnapper.fandom.com/wiki/Game_Download
Note that if you do decide to play it, make sure you read the Requirements section of that page.
