It was made with Unity, Photoshop and Gimp, Blender and using Trello and Git for managment. We released the Jam build as a Windows executable although we had initially planned to do it as a WebGL version. This didn’t work out due to scaling issues between the Itch.io app and Unity, though the performance and everything else was good in the browser.
I’ll making a self-hosted WebGL build here to see if that doesn’t have the problems we encountered during the Jam.
Edit: The bug has been fixed and an upload v1.2 of the game is now available.
