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/day in the week to Aug 6 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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 really wanted to like this game. On paper, OYASUMII, seemed like it'd be right up my alley. Unfortunately, after beating it I can't help but feel unfulfilled and ultimately disappointed. The devs clearly have a talent for crafting impressive visuals and atmosphere, but the gameplay is, if I'm being brutally honest, kinda terrible. It's basically a walking simulator with extra steps. In between the more impressive looking areas that feature some very light platforming, the game leads you down a linear path of square corridors, painfully slow swimming sections and mazes that only exist to pad out an already short game. Occasionally there are places to explore off the beaten path, but there is no real reason to do so. The game could've implemented a double jump and dash to make the platforming sections more involved, but instead (and somewhat bizarrely) opted to have little buttons that do all the platforming for you. The story comes off an unfocused and at times pretentious mess. Much like a kid who's just taken an interest in philosophy, the narrative of OYASUMII seems like it has a lot it wants to say, without really saying anything. There's a fine line between inspiration and straight up copying, and most of the games references fall into the latter category. At the end, my takeaway was that OYASUMII mostly serves as a vessel for the devs desire to make some cool references to their favorite games and movies, with everything else being an afterthought.

play as (presumably) legally distinct madotsuki and go on a 'quest' through very linear half life map and also very linear mario 64 levels with insane visual filters to simulate what it feels like to be an oled screen suffering from burn-in. all the while, asriel himself from undertale drops vague exposition on you occasionally. only thing i liked was the music. while i got the 'bad' end, i dont really care to play more as the game is a walking sim with no interesting exploration.
This game was fun! I finished it in 1.5 hours and I got the good ending. Still missing three achievements including the bad ending so I'm going to play again. I love the retro galaxy feel and the trippy liminal vibe. I didn't think any of the levels were too hard and I stink at platform jumping ha!
Oyasumii seemed to have a lot going for it with it's stylized visuals and environments. Very quickly you're thrown into a story that is shrouded in mystery, but the more you continue the more nothing is ever really explained. Instead everything becomes further obscured and cryptic to the point where your entire reason for playing the game feels meaningless. I was excited for it to all click in the end, but sadly it did not. Instead I played through a narrative that just felt pretentious, like it had this big philosophical message for me without saying anything at all.
Another bad ending xD What is really funny is that I instantly bought the game when it was released, dropped it and a year later finally managed to finish it. This game is almost perfect if you don’t think too much about the story or whether everything makes sense. It's literally what anemoia is. You just can't understand it, you can only feel it. The visuals are great, but the audio.. IT IS what really stands out. The music and sound effects do SO MUCH for the atmosphere, even the flashlight that I was spamming throughout the whole gameplay. At the same time, I can't call this game unique cause nowadays there are lots of games in that cute-dark style but OYASUMII feels really eerie and liminal in the best way. If you like a bit of creepiness in liminal horror games with amazing atmosphere - this one is definitely worth playing.
reminded me of Yume Nikki but without NPCs, good soundtrack.
HAVING A JAPANESE WORD AS YOUR TITLE DOESN'T MAKE YOU A HORROR GAME RESKINNING MARIO 64 LEVELS DOESN'T MAKE YOU A HORROR GAME QUOTING HALF LIFE DOESN'T MAKE YOU A HORROR GAME PIXEL FILTERS DON'T MAKE YOU UNIQUE AND QUIRKY SPOUTING RANDOM NONSENSE DOESN'T MAKE YOUR STORY INTERESTING love when indie games insist on themselves so much the gameplay devolves into random cryptic BS and "quirky" references. no horror. no intrigue, just cliched slop.
I like the references to the classic games but with an horror hint; the levels have a specific low-poly aesthetic that I really appreciate. I liked the level in the wood with giant mushrooms and the rainy dark level a lot. Maybe it's a bit short; I would have liked to explore more levels with different aesthetics. I think the game's strong point are the visuals rather than the gameplay itself 𓋼𓍊 𓆏 𓍊𓋼𓍊.☆☆.𓋼𓍊 𓆏 𓍊𓋼𓍊.☆☆.𓋼𓍊 𓆏 𓍊𓋼𓍊.𓋼𓍊 𓆏 𓍊𓋼𓍊.☆☆.𓋼𓍊 𓆏 𓍊𓋼𓍊.☆☆.𓋼𓍊 𓆏 𓍊𓋼𓍊.
