Gates the score. Weak reviews cap it, and nothing reaches BANGER without strong ones
MonetizationNone
Checked: no in-game purchases or loot boxes. That earns a small credit unless Steam lists in-app purchases

The value story

July 2025 is where it bottomed out, at $1.99. 70 discounts in the 7 years on record. They run about 35 percent off, roughly 5 weeks apart.

Against its own genre it lands in the top 16 percent on value. It is pricier than 83 percent of its genre, and better reviewed than 78 percent. Among the games that feel like it, Wizard of Legend ($15.99, scores 77) beats it on value, while it beats Dungeon Souls ($12.99, scores 37).

The press gave it 79; the people who bought it give it 90 percent. An 11-point gap in the buyer's favour.

9 of the 800 Steam-purchase reviews sampled here come from buyers who refunded the game, sampled from reviews written March 2022 to September 2026. Inside the two-hour refund window, 60 percent of the 466 reviews written there were positive, against 90 percent overall, and those are 5 percent of everything written about it.

HowLongToBeat players log 17.9 hours as a typical playtime, and completionists log 63, 3.5 times as much.

It carries Valve's Deck Verified rating, which is the one that means it just works.

No achievement in this game marks the ending, so there is no finish rate. The curve runs from the most-unlocked achievement to the rarest, and its shape is where players stop. Steam global achievements

What players say

Another roguelite where the grind is the content instead of the consolation. Good roguelites make failure teach you something. This one makes failure pay an instalment. The runs aren't a school, they're a shift. Time is the only thing a roguelite can actually take from you, and this one bills by the hour. Every currency in this game can be farmed. The one it spends can't be. That's the entire objection, and no...
