The Level Editor for No Time To Explain is now live in beta!
Here's a quick tutorial on how to use it. It's located in the final credits screen as pictured, and on top of the houses in Worlds.
For now you can access user levels from within the game. You can create and publish levels, and the editor is fully functional.
It will soon be set to public for everyone to rate/comment levels within the Steam Workshop.
Head onto the forum to give feedback. We'll be working for several weeks on improving No Time To Explain, so feedback is highly appreciated!
