The value story

June 2021 is where it bottomed out, at $0.99. 55 discounts in the 7 years on record. They run about 50 percent off, roughly 6 weeks apart.

Value puts it in the top 1 percent of the games it competes with. It is cheaper than 63 percent of its genre, and better reviewed than 96 percent. Among the games that feel like it, Cube Escape: Paradox (free, scores 93) beats it on value, while it beats True Fear: Forsaken Souls Part 1 ($8.99, scores 70).

The math says it holds its tier up to $7.21, and you are being asked for $4.99.
