There are two developer-made levels to get you started
If there’s one thing I want from Human: Fall Flat, it’s more of it. The wobbly co-op platformer never fails to crack me up. We’re getting official new levels this year, and there’s an opportunity for unofficial ones too. Human: Fall Flat now has Steam Workshop support for mods, including skins and levels.
To get creators started, No Brakes Games has whipped up a Beginner and Intermediate level to try out. The latter “has a totally different aesthetic to the levels in the core game, as the intention here is to show what else can be done using prefabs, node graph knowledge, and basic ProBuilder.”
So far, the Human: Fall Flat page is full of user-made character skins like Spider-Man and “Anime,” but given how popular the game is, it shouldn’t take long at all before the Workshop offers more levels.
My dream scenario is for the best custom levels to make it over to the console versions of the game down the road. That move wouldn’t be unprecedented, but I probably shouldn’t hold my breath.
For more on modding, the developers have put together a primer.
