About

A surreal, short-form puzzle adventure / horror game built for the GameBoy, POCKET MYSTERY EP DX updates the original POCKET MYSTERY EP with full color graphics, re-designed puzzles, updated music and sound effects, and additional content.
A STRANGE MURDER: As Detective Walker Rylance, explore the mysterious Minerva’s Nocturne hotel, investigating the locked-room murder of four colleagues. Nothing is quite as it seems, however.
A COLORFUL CAST OF CHARACTERS: Interview the colorful staff of the hotel - from the sophisticated concierge to the hyper-anxious cleaning staff and beyond. Relive the final moments of the victims and learn about who they are and their relations to each other.
DESIGNED FOR THE GAMEBOY: Built in GameBoy Studio, POCKET MYSTERY EP DX was originally built for, and is playable on, Game Boy Color. We’re not just riffing on the aesthetics of GameBoy games, this is built for the actual hardware.
ESCAPE A LIMINAL SPACE: Solve puzzles in a mysterious place seemingly inside the hotel, pushing blocks, activating switches, and more to escape a mysterious killer.

Development of POCKET MYSTERY EP began in summer 2022 in Game Boy Studio and released about a year and a half later on Itch in December 2023. Its development was honestly frustrating and didn’t quite go as planned. Rather than giving up, the game was re-configured to try and acknowledge the difficult development.
In August 2024, with a variety of improvements and updates to Game Boy Studio, the idea to update the game, replete with GameBoy Color support, was sparked. This deluxe, or DX, re-release doesn’t aim to fully deliver on the game’s original vision, but it does seek to fix bugs, update the music and sounds, and add some additional content hinting at what might’ve been.
This isn’t the end for POCKET MYSTERY EP either. A full remake, titled Nocturne: POCKET MYSTERY Remixed, is in development targeting a 2026 release.

"POCKET MYSTERY EP DX" is A very mediocre and failed attempt to make a murder mystery for the Nintendo GameBoy... and this is fine and I hope the GameBoy launch went really well, despite this launching in 2024. For some inexplicable reason it was also launched on gaming PCs. Gaming PCs which are not limited to the stupidly low resolution, low fidelity of the GameBoy handheld console appliance. As a result, this immediately fails all technical requirements that any PC game must exceed in order to be recommendable to PC gamers. The plot follows a detective reliving the final moments of his colleagues so you can piece together why they got murdered. Gameplay is a lot of clicking through badly written narrative, moving around, and a little bit of Sokoban puzzle stuff. In fact a lot of work went into this failure, but working hard on something that's immediately flawed because of the obsolete 1:1 low resolution display (no 4K, 16:9 here and that's unacceptable) is just a huge waste of time. Might as well spend 5 years writing a book then burn the only copy. There's an overwhelming amount of mediocre Visual Novel/E-book style cutscenes in this game. The developers failed one of the most basic, fundamental requirements of game design.. "Show, don't tell." So you'll spend a huge amount of time not playing the game, but clicking through endless lines of poorly written VN text cutscenes because the developers couldn't work out how to relate their narrative through the game mechanics, and decided instead it would be better to compete with reading a book for your time. We're here to play games, not read through hours of garbage intersituals. Your gaming rig is not a Kindle. This features really godawful pixelcrap "art" instead of real graphics. It's hard to say if this was because the developer didn't have the skill to do the job of creating 3D visuals, or couldn't afford to hire someone who does, but it also doesn't matter. What matters is that this looks much worse than most other games because of that decision, and that's a major deterrent to gamers. Games like Terraria and Stardew Valley succeeded [i]despite[/i] the bad graphics, not because of them. Let's look at the price and what kind of value this actually offers gamers. This is "free" enough (not every "free" game in the "free" section is truly free, there's usually some hidden price tag), at least you won't be expected to spend any more money after you download this, but just because something is free doesn't mean it's good, and the cost of a game is more than just financial, your time is valuable too. A peak of [b]3 concurrent players[/b] (according to SteamDB) for a "free" game is a disastrous public reception. Out of 130 million potential players here on Steam, almost nobody was interested. Even though this is "free". That level of rejection speaks a lot for the quality of the game. Bearing in mind that free games don't add +1 to your game collector count, should you bother adding this to your library and downloading it? This isn't good enough for me to suggest PC gamers spend their time and hard drive space on. There's thousands of better alternatives on Steam more worthy of your time.

Игра 'POCKET MYSTERY EP DX' - очаровательная и увлекательная смесь визуальной новеллы и детективной головоломки, которая затягивает с первых минут. Пиксельная графика выполнена с любовью и создает уютную, но в то же время немного тревожную атмосферу. Сюжет, хоть и не самый оригинальный, разворачивается достаточно интересно, чтобы держать в напряжении до самого конца. Головоломки умеренно сложные и требуют внимательности к деталям, а не простого перебора вариантов. Сбор улик и допрос свидетелей реализованы достаточно просто, но эффективно. Персонажи, несмотря на свою пиксельную природу, получились довольно живыми и запоминающимися, каждый со своими секретами и мотивами. Отдельно стоит отметить приятное звуковое сопровождение, которое отлично дополняет атмосферу игры. 'POCKET MYSTERY EP DX' не претендует на звание шедевра, но это отличный выбор для тех, кто ищет короткую, но увлекательную детективную историю, которую можно пройти за пару вечеров. Единственный минус - хотелось бы больше контента и загадок, но за свою цену игра более чем оправдывает ожидания.
This game held my interest for about five minutes and then I got so bored I quit.
