That was the plan! There'd be an in game editor and a textfield that takes a level data json to build the custom level... Unfortunately the plan failed... The rudimentary editor I made for this game only worked for long enough to make it and then it gave up the ghost because of a massive bug I never fixed (or really looked into). It wasn't presentable anyway. Making a proper public facing editor takes both time and effort that feels like it's not worth it for a little game like this. I do have another project planned that will be reading ldtk output for level data, so I won't have to make an editor myself. Still it might take a while to find time. Browser games aren't big anymore and it's pretty hard to justify wasting too much time on one.
