I've always found Google Slides to be a great way to create cute, personal games. It requires no coding, and anyone can play them easily in their browser. Seeing what people are able to do with a simple presentation (PowerPoint, if you will) has been repeatedly eye-opening every time I've seen one.

I'm a bit worried that Google Slides-games will fall out of fashion now ;(

Never heard of this. Is there an example of the best of the genre? I assume these are point-and-click adventures?

Tangentially related, have a look at Downpour, you might like it, if you like making ppt games! https://downpour.games/
