NGU is really fun, at least I like what I remember of it yet not sure what to do with that atm.
someone who's a big fan of Tower of the sorcerer is LAWatson who made I wanna Lockpick, and indeed that is the popular iteration of it in puzzle games atm.. yea not even remotely casual though apart from via love of pure math, lots of paradigm shifts at least.. really I am just in kindof a creative rut, it is actually a great game, begging the question of such greatness as predicated on creativeinspiration, notwithstanding..
