The rest are somewhat similar.

Misao was made my the same person who made Mad Father (it was made first), and The Witch's House follows the same principle of puzzles and your occasional scare.

Ib is a bit different but fundamentally is a creepy rpg game with puzzles, definitely worth a look if you liked any of the others.

Yume Nikki is a thing which you grow to love I guess, there're quite a lot of games inspired by it which stand pretty well on their own and could do with a look in if you're into the exploration type of game.
