About this game

Play through windows

Drag and drop windows to explore the world

Open multiple windows for interaction

Each window contains its own distinct gameplay content.

Characters can traverse windows to travel between different window worlds.

Utilize various mechanics to create unique differences between each window's world.

Employ a multi-window, multi-game mindset to solve puzzles and find exits.

This game was built using Unity (which lacks native window creation) and employs numerous incredible techniques to deliver an absolutely unique gaming experience.

Add it to your wishlist now—the full version is in development.

(Note: The current demo is an early build and differs significantly from the screenshots shown here. A new demo will be released with a proper update.)

    A new internal test version has been uploaded

    If you activated the internal test CDK I provided and haven't deleted the game, you've probably noticed it suddenly updated by 100MB out of nowhere. Yes, after wrapping up school matters, I came back to update the game. What's available for download now is entirely new content designed recently—a fresh start that scrapped much of the previous design. If you're interested, please give it a try.I distributed only a very limited number of internal test CDKs for this game. Theoretically, this update and announcement should be virtually impossible for anyone to see, and I never expected them to be discovered. But who knows?Alright, Steam doesn't have an announcement feature exclusively for “players who own the game,” so I have no idea where you might have seen this notice. I'll take this opportunity to briefly cover the details of this update and outline my plans moving forward.In this update, I've completely removed the jumping mechanic from the demo version. The previous version was far too prone to bugs, likely because the action elements were overemphasized. Starting fresh without jumping, I'll focus on developing more levels and mechanics, aiming to push the game toward puzzle-solving gameplay.Currently, I still haven't added music, sound effects, or refined the game feel. The story remains in its prototype stage. However, I've incorporated some shader effects into the game, hoping they'll enhance the overall atmosphere.Testing revealed significant performance issues when running the game across multiple monitors simultaneously. I currently have no solution for this and recommend avoiding such setups.The demo version won't be updated in the near future. I plan to refine the story, sound effects, localization, and other elements before releasing a definitive playable version.Well ,still translated with DeepL.com. I tried, but my English is no good. (Origin Chinese version: 如果你激活了我提供的内部测试CDK并且一直没删这个游戏,我想你应该发现了这款游戏突然莫名其妙更新了100MB,是的,我在把学校的事情处理完后,回来更新游戏了。现在所能下载的到的,就是最近设计...

    Next Fest is over, thank you for your support!

    Thanks to all players, the Steam Next Fest is now over and I'm glad that the game demo was able to get over thousand playthroughs and number of wishlists. It's actually a pity that there was supposed to be more content here and more bug fixes for different computer environments, but it was just too much effort to go through to make a game like this, and ultimately it didn't make it in time to catch up with the updates before Next Fest started. But even so, the game has gotten so much attention, and I really thank you all for that. Theoretically, each game should only be able to participate in the Next Fest once, and the current amount of content in the game is completely unsupportable for a release anytime soon. As of now, so please be patient, maybe a few months, maybe wait a year or even a few years until I'm convinced that the game is worth playing. I would especially like to recommend Outcore, which is also a game with a unique gameplay similar to my game and has been officially released, to all those who can't get enough of it after playing my game. I'll be updating the demo version on an ongoing basis in the future. However, without the Steam Next Fest, it's not easy to let you all know about demo updates. The good thing is that the game will be officially released one day, so maybe it's better for you to ignore the various edges of the development process and go straight to the final version, so please wait for that day. If there's anything you'd like to talk about, just do it in the Steam discussion forums. A short update plan: fixing various bugs, redesigning the game's levels, experimenting with more forms of content, and figuring out how to make music and art. Looking forward to seeing you in the future with more content for MultiWindows. (Here are the original articles and I'll post them. I hope there are no mistakes in the translation. 感谢各位玩家的游玩,现在新品节已经结束了,也很高兴游戏demo能够得到上千的游玩人数和愿望单数量。其实也很遗憾,原本这里应该有更多内容,也有更多针对不同电脑环境的bug修复,但去制作这样一款游戏实在是太花费精力,最终没能及时在新品节开始前...

    Folder Name Fix

    Previously the installation folder name for the Demo version of the game was incorrectly set, resulting in the game's installation folder name containing Chinese. This caused some parts of the game to not work properly, and I have now removed the Chinese. If you have already installed the Demo version of the game, please reinstall it again to take effect the changes to the game folder (or just delete the Chinese from the folder and start the game from the game directory).

    Early demo version now available

    This demo version was also entered into the Steam Next Festival, although in theory this wasn't a good choice, after all, this version is meaty and rough right now. But I'm a personal liberal game developer, I don't really like to follow any theories, it's my vision to get people to play this game earlier. Of course, I'll keep up with subsequent updates, and I'll try to update the demo version over time, updating the demo game once I've saved up a sufficient wave of content and continuing to refine the official version in the meantime. I'm not sure if the code for this game will work properly on a player's computer, so feel free to contact me if you run into any problems. I can be found either through reviews, Steam discussions, or my personal social media accounts. ( I haven't got x or discord account, maybe contect me on itchio ) * translate by DeepL

    Very preemptive beta play notes 非常抢先的测试版本游玩注意事项

    This version of the game is an early playtest and only those who have received an activation serial number will have the opportunity to play this version of the game. The number of activation serials issued is very small, and is tentatively intended to be permanent and will not be withdrawn (if something unexpected happens, I will try to re-issue them). If you are reading this, you are indeed a player I recognize and respect, and I have the utmost respect for you. Because this game still contains a certain degree of bugs, the next is the game play notes: 1, this game does not support multiple monitors, if your current computer has more than one monitor, it may lead to the size of the open window is very small. If you have more than one monitor, it may cause the open window size to be extremely small. Since the developer does not have multiple monitors at the moment, he can't fix this bug, so please disable other monitors and keep only one monitor. 2、Please make sure that the game directory is located in the English path, if you store the game directory path contains Chinese, it may lead to a small bug (specifically manifested as something can not be dragged). 3、Please try to play under Win10/11, we are not sure about the compatibility of the game under Win10. 4, there are still other bugs in the game, for example, when the character turns gray, please click on the window, otherwise the character's collision cannot be executed correctly. If you encounter bugs or encounter obstacles in the gameplay, you are also welcome to contact the developers in various ways.QQ: 1441529822, machine core or B station private letter will be looked at from time to time. 5, if you think it is fun, you are very encouraged to spread the game content, whether it is recommended to your friends or send the game content to social media. 6, all game content, including art, level design and so on, are not representative of the official version of the game content, subject to the deadline and n...
