Gearing up for Steam Next Fest.
The "Main" level collection now lives in a walkable level. In order to open the gates and go to new areas, you have to beat the number of levels shown above the gates. The old level select is now the "Collections" menu, here you can find your custom levels, and also the levels from the main collection. In order to play those from the main collection, you have to beat them in the world first.
