Serena is a dark, gruesome adventure game, portraying loss and misery.
You play a husband, in a very small wooden house in the middle of the woods, trying to get a grasp of your memories. Everything you look at triggers thoughts, memories, or confusion, most especially a photograph of you and your wife, with her face entirely missing. You can't remember her properly, and you can't work out why. By exploring all the items and furniture in the home, you attempt to put the pieces back together. Memories start to change after you trigger certain moments.
The game doesn't have a very original story to tell and the ending is enormously apparent.
The game engine is also a big thumbs-down - having to be transitioned from spot to spot feels archaic. Also there is no option to save your progress - even though it's a very short game (around 1 hour of gameplay), it would have been nice to at least get a warning message if you attempt to quit (or accidentally press the Esc button).
For a free game, Serena isn’t a bad use of one’s time, but it’s hard not to think that this game could’ve been better.
