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 Sep 8 → 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 2,400 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.
About
Trapped in a haunted high school, Kasuga must uncover buried secrets to escape the terror-filled halls.

Kasuga, a popular student, wakes up to find herself inexplicably trapped inside her school after dark. The eerie silence and shadowy corridors are far removed from the bustling, lively atmosphere she knows. Worse yet, her memory of how she ended up there is a blank slate.
Desperate to escape, Kasuga begins exploring the seemingly abandoned building, only to encounter chilling phenomena. Cryptic text messages flood her smartphone. Strange entities begin to manifest.
Piece by piece, Kasuga must uncover the truth about her school, her peers, and even herself. But beware: nothing is as it seems, and some secrets are better left buried.

A Spine-Chilling Horror Adventure: Explore a haunted high school filled with eerie sights, cryptic clues, and unsettling twists that will keep you on edge.
Interactive Smartphone Gameplay: Use Kasuga's smartphone to log clues, capture photos, and receive unsettling messages as you unravel the mysteries surrounding her imprisonment.
Dynamic Perspective Switching: Experience the tension from every angle—switch seamlessly between 3rd and 1st person views to fully immerse yourself in the environment.
Anime-Style 3D Graphics: Dive into a world that combines stunning visuals with a deeply atmospheric setting, creating a perfect blend of beauty and dread.
Will you help Kasuga escape the nightmare... or will you succumb to it?

雰囲気は良かったです! 謎解きも難しすぎず簡単すぎずで良い塩梅でした! ただ適役で出てきた存在の背景や、エンディングについての内容が薄く理解に苦しむ終わり方をしました。 ゲーム内容としてすごくよかったです。
I was so excited to play this game and it did not disappoint. Spooky/horror games that are very puzzle intensive usually are not my type of game because the puzzles tend to be difficult and take me out of enjoying the game and the story. This game however did NOT do that. The puzzles were not super simple and did take some thought but were still enjoyable to the overall game. And I really liked the story the game had too. After completing the game I realized it had quickly become a new favorite of mine. Would definitely recommend.

雰囲気めっちゃ良きです! めちゃくちゃ探したのですが、あと1つの像がどこにあるのかわからないのと、Angelの意味をどなたか教えてください……
Интересные конкурсы, и тамада прикольный, но за головоломки с этими камнями жопу надеру разрабу
[h3]Review for [b]High School Dirty Secrets[/b] - [i]Mixed but Leaning Positive[/i][/h3] [b][i]Overall, this is an average game that's playable and delivers a basic horror experience, but it's dragged down by a ton of bugs that stretched my playtime to over 10 hours (way beyond the expected 2-4 hours). Still, it has some charm if you can push through.[/i][/b] [h3][b]* Pros:[/b][/h3] [i]- Performance:[/i] Runs fine without crashes—stable enough to get through. [i]- Graphics:[/i] The 3D anime art style is okay and fits the vibe—6.5/10. [i]- Horror Atmosphere:[/i] Builds decent tension; acceptable for what it is—6/10. [i]- Story:[/i] Nothing standout, just standard fare—5/10. [i]- BGM & SFX:[/i] Solid and supportive—6/10. [i]- Gameplay:[/i] Straightforward puzzle-solving loop (encounter puzzle → hunt items/clues → solve → get key/item → repeat). It's repetitive from start to finish but gets the job done—5/10. [h3][b]* Cons and Suggestions:[/b][/h3] [i]- UI/UX Tweaks:[/i] + [b]The 'Options' menu under 'Gameplay' feels misplaced[/b]—stuff like FPS cap, V-Sync, and resolution should be under 'Graphics/Display'. + [b]'Reset Data' is buried in Options[/b]; move it to the main menu or just call it 'New Game'. - With such a short runtime, [b]manual saves are a must[/b]—add them to avoid frustration. - [b]Puzzles are mostly easy[/b]; later ones just hide items farther away with extra steps, not real challenge. - Switching between 1st-person and 3rd-person views feels unnecessary—interactions/puzzles only work in 1st-person anyway, so 3rd-person is just for watching your character walk. [b][i]- Bugs/Glitches Galore (Forced Multiple Restarts):[/i][/b] 1. Exiting the swimming pool classroom locks movement—keyboard and controller both fail. Had to menu → load → replay. 2. Interacting with objects: Cursor/controller sometimes doesn't register even when perfectly aimed. 3. [Story Spoiler] [spoiler]On the rooftop after 'Try to Remember' event—if you outrun the ghost girl, story gets stuck. Reload doesn't fix; full restart required.[/spoiler] 4. [Story Spoiler] [spoiler]In 'Redemption' ending, rushing through mirrors causes load failures—some don't transition, leaving you glitched.[/i][/b][/spoiler] 5. Bathroom ghost message on floor 3: [i]Interact → get message → read → ghost doesn't despawn.[/i] Reload and replay the section. [b][i]Despite the jank, it's a quick, okay horror fix with anime flair if you're patient with bugs. Devs, please patch those glitches.[/i][/b]
Wow, huge praise to the team behind the game. It was so much fun to play, and the atmosphere, puzzles, and story were fantastic. The sound effects were well-balanced and always created a menacing atmosphere, which personally made me even more scared. What you learn and everything about the story (I won't spoil it here, you'll have to find out for yourselves) really surprised me. The graphics and controls were great, and the ability to switch perspectives was a brilliant idea. The fact that you can't defend yourself isn't a problem, as the game is really well-designed for it, and there are some great jump scares. If you like anime, especially waifus, and enjoy horror and school themes, you'll love this game. I really hope there will be another game like this someday. <3 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Wow, Riesen Lob an das Team dahinter für das Game. Es hat mega Spaß gemacht es zu spielen und auch die Atmosphäre, die Rätsel und die Story waren, super. Die Sounds waren gut abgestimmt und haben immer eine bedrohliche Atmosphäre mitgegeben, was mir persöhnlich, schon was mehr Angst gemacht hat. Was man erfährt und alles von der story, (ich spoiler hier nicht, da müssen die anderen selbst rausfinden.) hat mich mega überrascht. Die Grafik und Steuerung waren super und auch die Pespektive die man immer wechseln kann, super Idee. Das man hier sich nicht verteidigen kann, macht nichts aus, da es im Spiel wirklich angepasst dafür ist und guter Erschrecker dabei sind. Wer gern Animes mag, auch gerne mal Waifus und das zusammen in Horror und Schulthema mag, kommt hier auf seine Kosten. Hoffe doch, das es vielleicht irgendwann ein weiteres Game in diese Richtung geben wird. <3
短篇校园恐怖的擦边尝试 《High School Dirty Secrets》是 Mitsuki Game Studio 制作的 3D 恐怖解谜游戏。玩家扮演紫发少女春日,在封闭的深夜校园醒来,一边躲避女鬼追杀,一边探索学校隐藏的黑暗秘密。 游戏选校园做设定上的舞台,算是很经典的选择了吧。闪烁的灯光、狭窄的手电视野,加上不时出现的怪响,恐怖氛围拉得很足。 游戏可切换视角,第一人称视角下视野受限,很容易让人绷紧神经。核心玩法是传统的找道具、解谜、开门,然后循环。手机是全程的核心道具,既能当手电筒照明,也能接收诡异消息,还能拍下线索存进相册。 谜题难度不高,大多靠观察和记忆就能解开,不会故意刁难玩家。追逐战压力不大。遇到女鬼就找柜子躲,等声音消失再出来,别当面钻柜子就不会出事。 死亡惩罚很低,被抓住后只会回到起点,背包里的道具全部保留,不用反复收集。 游戏带有不少擦边内容。可以收集不同款式的内衣,女鬼穿着暴露,泳池关卡有泳衣造型,死亡演出也有特殊设计。但这些内容只是点缀,游戏主体还是恐怖探索。 部分场景有 bug,比如泳池关卡后操作锁死、互动判定不准,容易被迫重玩片段。地图复用较多,后期谜题只是拉长找东西的路线,缺乏新意。 优化表现尚可,能流畅运行。正常通关大概 2 到 3 小时,全收集也只要 3 到 4 小时,属于短小精悍的类型。 总的来说,这是一款合格的短篇二次元恐怖游戏。氛围在线,门槛不高,适合轻度恐怖爱好者。如果你对校园题材加擦边元素感兴趣,可以一试。[quote]关注「[url=https://steamcommunity.com/groups/45531088] 鸢尾花 [/url]」[/quote][u][b]致那一朵未至鸢尾花[/b][/u]
I enjoyed this game quite a bit. It's the second game I've played of the dev's (first being Waifu Impact) and I was looking forward to this release and am happy with the game overalll! I also had a good time getting scared lol My only complaint is the basement maze. I didn't like that, esp the room with the bodies. I got bodied there myself a number of times lol. it's just a real small room, the ghost spawns real fast, and the symbols were real hard for me to find and read. The only other addition I'd like to see is something like a checkbox for the collectibles. I found 3 of them (maybe 4? idr) but I had no way of knowing if I got them all. I thought I was pretty thorough looking everywhere, but I can't help but feel I missed some or a lot. I would have loved a checkbox or title gallery or smth for getting them to show progress. I know they're optional, but still. A fun game and a quick "chase horror" experience with some light puzzles :)
