What drives the score

How to read this

Every input gets a grade, S to D, read from the buyer's side. The score is multiplicative, so an input only counts as raising when it sits near the top of its own scale. Anything with real room left is holding the score back, because that room is the gap to 100. ▲ marks a lift, ▼ a drag or a dock, ? an input we do not have, • a fact this genre's score does not use. The exact weights stay secret.

The value story

The lowest price on record is $4.64, set in March 2024. 20 discounts in the 7 years on record. They run about 50 percent off, roughly 14 weeks apart. Today it is at full price. The last sale was about 13 weeks ago, and on this game's rhythm the next one tends to arrive within 14 weeks.

On value it sits in the top 37 percent of its genre. It is pricier than 66 percent of its genre. Among the games that feel like it, The Basement Collection ($3.99, scores 74) beats it on value, while it beats Overture ($4.99, scores 40).

73 from critics against 81 percent from players, and the player number comes from people who own the game.

Of the 755 Steam-purchase reviews this site sampled, 11 come from buyers who refunded the game, sampled from reviews written March 2020 to September 2026. Inside the two-hour refund window, 54 percent of the 755 reviews written there were positive, against 81 percent overall, and those are 13 percent of everything written about it.

HowLongToBeat players log 8.8 hours as a typical playtime, and completionists log 38, 4.3 times as much.

What players say

If you're a fan of The Binding of Isaac, you'll likely get a kick out of it's prequel. Featuring pretty basic match 4 puzzle game mechanics, Bumbo's roguelike adventure may not be quite as crazy as Isaac's, but with a charming Cardboard based artstyle and some expansions on the Isaac storyline, this game is worth giving a look even if it won't keep you as busy as it's predecessor.

BUMBO GOT COIN i wish this game had more attention i feel like the throbbing domain(from Mewgenics) would really fit in this game
Sprouty_1Recommendedafter 23hJul 2026Read on Steam
It loads slowly, has been left untouched for around 5 years, any time i try to play it i feel like anything i do is useless and compels me to just play something else, even Isaac (whit some challenge based exceptions) and Mewgenics arn't that eager to make you give up that fast. only good thing i will say is that i appreciate it's contribution to the story of isaac and the visuals are REALLY cool, but it's not worth...

[![BANG Score](https://steambangers.com/api/badge/1148650)](https://steambangers.com/game/1148650/the-legend-of-bum-bo)

The BANG Score is one number for value, 0 to 100: price against how it reviews and how long it was built to be. It answers the money question and stops there; whether the game is for you is still your call.

Reviews set the ceiling and price moves you inside it, so a cheap game that reviews badly cannot climb. Ratings from few reviewers are shrunk toward the middle, so 100 percent from nine people does not outrank 96 percent from ninety thousand. Length comes from HowLongToBeat where it can be matched, measured against a per-genre floor so a five-hour narrative game is judged against other narrative games rather than against a sixty-hour RPG. Where no verified length exists the score says so and carries a dock, because the biggest input is then a guess. The full method, including where it is weak → Steam reviews as of Sep 15, price as of Sep 24.

A number here look wrong? Tell me what it got wrong and I will look at the inputs behind it.
