The value story

It has never been cheaper than $3.99. That was January 2025. It has been discounted 53 times in the 7 years tracked here, typically at 80 percent off, with about 6 weeks between sales.

Value puts it in the top 1 percent of the games it competes with. It is pricier than 90 percent of its genre, and better reviewed than 93 percent. Among the games that feel like it, Pentiment ($9.99, scores 92) beats it on value, while it beats Blacksad: Under the Skin ($19.99, scores 53).

Players rate it 91 percent positive over its lifetime, but the last 30 days run 82 percent. Something recent has soured the room. This site sampled 800 of its Steam-purchase reviews; 3 were written by buyers who refunded it, sampled from reviews written October 2021 to August 2026. Inside the two-hour refund window, 69 percent of the 272 reviews written there were positive, against 91 percent overall, and those are 3 percent of everything written about it.

Assuming you are one of the few people that would buy this game not enjoying a decent amount of "anime-esque" talk and jokes, if you stick through with this game you'll find that despite that you have an incredibly tightly written story, chock full of twists and turns that will keep you entertained until the end. And even though the gameplay is by all means non-existent, the quality of the narrative more than...

date i need you to lock in. stop arguing with the 12 year old child. stop trying to hit on the receptionist. date, are you listening? anyway i have a whole lot to say about the game. not quite sure where to begin. i guess with the characters? the cast hard carries the game. i'm not a huge fan of voice acting in general but they really cement the characters here and the directing and performances are top notch across...
