Prices
The United States storefront in every case, so this compares stores and not countries.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.14/day in the week to Aug 27 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Bumbum is a charming puzzle game that strikes the perfect balance of challenge and relaxation. Its colorful, cozy art and hilarious NPC interactions make every moment delightful, while its clever level design keeps you engaged without ever feeling stuck. The puzzles are satisfying to solve, often sparking 'aha' moments long after you’ve stepped away. While the concept is simple, its heartwarming charm and polished execution make it an absolute joy to play.
Giving a thumbs-up for now. I generally enjoy Sokoban-like games. The issue with this one is that you must land on the end square with a particular side of your "cube" facing down, but most blocks you move over disappear after you exit them. This requirement for positioning isn't the kind of puzzle I tend to enjoy, and in fact to me it makes some levels too prescriptive. That is, there might be multiple solutions--none of which, in my opinion, need to be trivial--but only one of them is acceptable because of this constraint. So far, this has been a mild annoyance on a few levels; on many, there really is only one solution and you naturally end up in the correct position after executing it. On a very small number of levels so far (at time of this review, I'm almost done with the second "world"), the game gives you an area near the exit where blocks will not disappear and thus you can reposition yourself without any problems. I wish more levels had an area like this.

It's a decent Sokoban about shooting lasers into your own butt. To complicate matters, you are also a cube, so rolling hi-jinks ensue to ensure that your butt is correctly aligned and ready to take a laser-pounding.
None of us ask to be born. We are pulled out of the ether, into a realm where there is one rule above all: Chaos is the order of the universe. Our world is often cruel and unfair. However, it is our great onus as human beings to make order out of chaos. That we must make a collective effort to better society at large. Often it is not easy to do good, but it can be trained. It can develop like a muscle that becomes steeled as we make bigger and better acts of goodwill. Like any practice it requires making small steps to achieve results. One small positive change to bring in this world, would be to recommend Billy Bumbum, the silly butt puzzle game to a friend, so that this underappreciated gem gets more attention. Be the change you want to be in this world.
Good funny puzzle exceptionally perfect with beer
不是纯粹的滚方块,更多的是猜测作者的意图。 猜出作者想要我走的路线后,就几乎不需要思考了,也不需要考虑屁股的朝向了,因为只要按着作者的思路走,屁股就会滚到正确的位置。 我不喜欢这种教我玩游戏的游戏。
I got this one in a bundle and played it almost more for giggles than for a game. The first levels were exactly what I thought it would be: a fairly simple "roll so the correct part of you gets in the exit" game. Okay, with mostly disappearing blocks and lasers, but nothing overly fancy. I thought. Thing is: the game's absurd premise and theme (cube katamari with some butt fixation) doesn't make you presume the puzzles are hard or require more than a few tries. It's on this part that this game is a hidden gem. The later levels show ingenuinity, clever thought and - admitted - some frustration on my behalf. But on that last part: SOME frustration is fine, especially if it leads to "ooh, of COURSE!!!" moments when the solution finally snaps. Thus far I haven't encountered much levels that seemed random or went overly chaotic. I'm not that far but I've seen some good level designs that made the game worth it in itself. The theme is, for me, a miss. But nonetheless, I can easily recommend this game to puzzle lovers.
