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.

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 idea and want to see it grow more recommend his to anyone who thinks they are good at platforming
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
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.
'spretty good
tldr; fun, well performing, movement-mechanic based game with a surreal(?) and interesting story I love this game. The movement tech seems very well optimized with a skill ceiling that gets really high if you want it to, the only limiting factor for something like this is YOUR level of skill. You can quite easily feel and understand what you can and can't do. The tutorial(s), which although feel a bit short, are very well done. For people that haven't done much with SourceEngine movement-based gameplay, I think it's pretty good. I would NOT say that I am a pro at things like b-hopping or strafing but with how well it's designed it genuinely feels accomplishing when I do something that feels difficult every time. I love the artstyle. Brutalist structures, bottomless pits. I like how the shadows of the things close to you have the colors inverted. However, when you want to backtrack to a level, with how the style and the maps are designed it can get difficult, even with the echolocation ability (which doesn't highlight previously completed levels) even with that, I had a lot of fun And it runs perfectly on my very much non-gaming laptop. Personal biased stuff I had a moment of pause when I loaded up the game. For a moment, my mind flashed through blurry memories of when things were formatted like this. The weird grimy(?) feel of renders and drawings that I'd see on the front of a CD with a game on it. Had to actually put effort into reading the font that the game uses but I don't think that's something I mind. It's making me a bit emotional, really. I really didn't expect that I'd encounter an artstyle like this ever again. also the player character is fine as hell
