Great game, I wish there were more levels tho. Hopefully in the future as from the looks of it, it shouldn't be hard to make new ones once you have an idea for them.
Haha oh wow, that's interesting! Unfortunately as every puzzle is quite unique, it probably means exposing some scripting language to an editor. To be honest as this is a free game, and it was meant primarily as my foyer into game development, I wouldn't want to invest that much time into a "puzzle editor".
