Hypnagogia is one of the best looking games I ever played. If you are into "dream" games, this one is good, but there are some things you should keep in mind:

1. The game is very linear
2. The levels are short and self-contained, you never feel lost in a vast universe like some games make you feel, this one is compact, but well polished
3. The gameplay often involves some quick fetch quests, go from point A to point B, you will rarely get stuck for a very long time, something I consider a plus
4. This is a game to be appreciated, visually, take a look around, enjoy the view, the good art direction is the greatest aspect of the game
5.The gameplay itself is very simple, but it can get a little annoying sometimes. It is a first-person game with a lot of focus on platforming, which is a terrible combination.
