From Yandere Simulator Official Website

Is this game coming to Mac / Linux / Chromebook / PlayStation / Xbox / Nintendo / iPhone / Android / Atari?

At some point in the future, I may release Yandere Simulator on multiple platforms. However, right now, I am only releasing builds for Windows PC. There are two main reason for this:

1) I only have a Windows PC. I don't own any computers using the Mac or Linux operating systems. If I exported a Mac / Linux build, I'd have no way to test it. I'd just be throwing a build onto the Internet and praying that people can run it, with no real way to debug it if it doesn't work.

2) Yandere Simulator is developed using the Unity game engine. Within Unity, the process of switching from one platform (Windows) to another platform (Mac, Linux) requires Unity to re-import every one of the game's assets. See the box that appears onscreen, 1 minute and 21 seconds into this video?

For an empty Unity project, that box is only there for a few seconds. But, Yandere Simulator is a huge game with thousands of assets, so when I click that button, it hangs there for about 15 minutes. Exporting a new build takes 15 minutes, too. It's simply too time-consuming to export PC+Mac+Linux every time I want to make a new build, especially when I can't even test the Mac or Linux builds.

I can't justify working on multiple platforms right now; so I will be maintaining my focus exclusively on PC for the time being. I won't begin to consider exporting Mac or Linux builds of the game until after the first official rival is implemented.

Regarding the possibility of releasing Yandere Simulator on console...developing games for console is extremely expensive, so this is something that I can't promise unless Yandere Simulator is very financially successful, or unless I host a crowd-funding campaign to raise funds for releasing the game on other platforms.

Yandere Simulator may seem like a simple game on the surface, but it is actually an extremely complex game. It is extremely unlikely that a mobile device such as an iPhone or Android could ever run the full version of Yandere Simulator. In order to run on a mobile device, the game would have to be simplified so much that it wouldn't even be the same game anymore.
