Note i think something is bugged with the 2nd puzzle, the thing that views the pic on the third part blocks it, meaning you have no way of beating the 2nd puzzle, kind of preventing progression
Edit: I don't think there is a proper 3rd/4th game yet tho
Edit: there is a 3rd game, but the endings are in progress. The game is a bit jank so Im guessing it doesn't properly detect it as complete hm
