Tiles was the first Roku game that I decided to port to other platforms. After originally releasing on the Roku in 2016 then recreated it in MonoGame and released it on Steam in 2017. Then it was released on PS4/Xbox One in 2018.
Level sharing in Tiles is cross platform between PC <-> PS4 and PC <-> Xbox One, but not between PS4 <-> Xbox One. The Roku version of Tiles has it’s own separate pool of user created levels.
