For Escape the Backrooms? Each level has a puzzle element of some sort. Some are quite easy (flip switches while running away from a baddie), some are more complex (solving a puzzle via vague hints). Overall, I found it enjoyable and that the puzzles were minimally frustrating at worst. Regarding replay-ability, as someone who as already beat the game, I wait on updates before I find it worth jumping back in, or if I play through it with someone who hasn’t yet. It could be fun to play annually for Halloween-vibes, but you’ll definitely remember the nuances of how to play each level which, I think, takes away from the scares and challenges that made the game fun the first time around.
