Harold's Walk is the 3DS platformer I originally released before Automaton Lung.
The tone is very different and it features a lot of experimental + abstract stages. This PC port/remaster adds a lot of new content.
Please consider wishlisting it now to help the algorithm on Steam (you can do it from here with that little blue button below) :)
