If The Witness was too hard and too pretentious for you, you should try The Looker. It's a fun and fee parody. That doesn't mean that it hasn't its own fair share of tricky puzzles. But all beatable in an hour makes it way more approachable. There are new fun ideas and some neat meta moments. It isn't anything like the Stanley Parable but I see The Looker as the baby of The Witness and Stanley Parable with some great and random humour and a whacky strange world.
