I really love this movement! Have you ever considered adding some kind of level editor/creator? I'd love to see one implemented, there are so many things you could create with this!
a level editor is actually one of the big features I want to add to the free steam version of Eraser! I intend to release on steam with multiplayer first, then add more features post-launch. feel free to add it to your wishlist if you want to be notified when it goes live! https://store.steampowered.com/app/1819570/Eraser/
