Yes. Platform availability can vary depending on licensing and technical considerations. However, the goal is usually to reach as wide an audience as possible. So, you can expect to find sekai project visual novels on platforms where there is a significant demand for this genre, such as Steam for PC, and sometimes on Nintendo Switch as well.

I'm not entirely sure specifically what 'Showtime 1996 Bedtime Stories' is about. It could be a collection of bedtime stories presented in 1996 on Showtime. Maybe it features various fictional tales for kids to listen to before going to sleep.
To be honest, I don't have a definite answer. Sometimes shows take elements from real life and fictionalize them. It's hard to say for this one without more information.
