Puzles difíciles a veces en demasía, pero en general muy satisfactorio de jugar

Good puzzles most of the time but some are way way too obscure.
But the most disgusting thing is the walk speed. I could make a cup of tea before 100m walk is completed in this game.
It reminds of those cheap games where developers remove sprint and turn down walkspeed down to a crawl to make the game time longer.
-2 stars for that alone.

it's myst, the prequel to riven!
