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): 0.29/day in the week to Aug 8 → 1.86/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 2,400 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.

What a weird game. What if a winamp skin from 2004 was a metroid vania about bunnyhopping? This game is very fun, and fully aware of its own insanity. It's been a blast so far and the dev seems to be pouring both passion and talent into it.
Guides you through learning source movement. Challenges never seem impossible, just hard. Sound design rewards you for achieving higher speeds. The upgrades compliment each other rather than the first becoming completely obsolete. Just one issue: It's too short to justify being that good

I'm autistic about bhopping and this game felt good.I hope much more comes. Even if not much more comes, i'll be a stan. (but please more)
I ♥♥♥♥♥♥♥ love this game, it scratches the right kind of itch. The movement is so smooth and just love how there is no speed cap.
phenomenal... great visual style and sound design, good soundtrack, very fun and fluid gameplay... all i could ever ask for...
Прикольный микс старых B-HOP мапок с новыми механиками и сюжетным послевкусием
This Game Is The Most POWERFUL Game Of All Time. Buy This Game. Play This Game. Become POWERFUL.
someone gifted this to me and i thought it would be kinda boring, and i was right for the duration of the first area (i was stuck there for a while because im dumb) but then i realised that it was fun as hell, great game
I gotta be honest, its not that good. The Bhopping looks cool in the trailer, but it gets stale real quick. It just feels like a confusing walking simulator with annoying parkour. Making a jump feels almost random, because even if you have enough speed its hard to control when you jump, so you need to go all the way back to do it again.
I am now addicted to bhopping, thank you GEHIRN
