For 6 dollars you get a very interesting, but short, PSX style puzzle platformer. There is basically 0 horror in it though which is unfortunate. Voice acting was really good, same with the music!1 found this helpful
The Sirena Expedition is a short narrative game with puzzle platformer elements with a Lovecraftian backdrop. I'd say for the small price I paid for it, it's a nice little game that I enjoyed. It even comes with a remixed campaign with harder puzzles and a tweaked story. It's a neat hidden gem that I'd recommend for people interesting in something more focused on atmosphere and narrative. There were only issue I encountered during my entire gameplay. One came from signposting on certain box puzzles later in the game where (after I had correctly solved it and got a box needed for the larger puzzle) I was unsure if I needed to get more or not. This led to me wasting some time trying to solve a puzzle that I had already completed.1 found this helpful
