As a huge fan of Media Molecule, it was a delight when, on their weekly highlight stream, I saw them playing the game I made in Dreams. Even better, they said nice things about it!
The game is called Mini Astro in Timeland and is a platform-adventure I made with input from my kids. I did everything except character animations and music.
I may post more about how I made it – and possibly other stuff made with Dreams – later when the game is released.
