Good quiz but i personally don't consider the nightmare to be the easiest demon, the lightning road is easier imo and also if you want to see an actual free demon, you should play brainfugd by sputnix, a level where you have to program stuff to beat the level, and dim by sputnix, a 2d game where you have to escape a maze with obstacles, also only counting "normal" gd levels, electro house by danolex i consider to be easier than the nightmare, this is coming from someone with 37 demons
