The value story

It has never been cheaper than $2.99. That was June 2022. It has been discounted 73 times in the 7 years tracked here, typically at 75 percent off, with about 5 weeks between sales.

Value puts it in the top 9 percent of the games it competes with. It is pricier than 90 percent of its genre, and better reviewed than 90 percent. Among the games that feel like it, Bear With Me - Episode One (free, scores 67) beats it on value, while it beats Little Misfortune ($19.99, scores 59).

74 from critics against 90 percent from players, and the player number comes from people who own the game.

1 of the 470 Steam-purchase reviews sampled here comes from a buyer who refunded the game, sampled from reviews written March 2020 to August 2026. Inside the two-hour refund window, 64 percent of the 146 reviews written there were positive, against 90 percent overall, and those are 7 percent of everything written about it.

What players say

I loved this game . The story , the humour , the art , Kitteh...dang it, it was perfect. For me it goes straight next to Broken Sword series for my all time favorite adventure game. What an amazing Call of Cthulhu adventure , it had everything and more so . It was a pleasure to click and listen to all of the conversations and descriptions. For sure a game to replay in the future. If you like everything: -Lovecraft ...

One of the best cthulhu adventures written. The comedy is professional and not just "haha carzy people go weird". Lovecraft intended Cthulhu as a sci-fi myth and they picked up on that well. Story, dialogues, voiceacting, chapter design, puzzles, music, artwork - everything is so well done and put together. I was constantly torn between clicking everything and satisfying my burning curiosity how the story develops...

If you like games like Monkey Island but also like horror-spoofs (this feels niche) then this is an essential purchase. The characters are fun, the voice acting is great, and the art style is spot-on.
