Hello, thanks for your question. The game is EXTREMELY early in development but questions are always encouraged.
Currently there are only windows files for YujinxTeki, due to the simplicity and ease of making them whenever I update the game I simply use a file compatible for windows.
However, not long ago I uploaded the game in HTML5 format, compatible with all devices from PC to Mobile. The only reason I stopped is that the HTML5 version of the game was buggy, especially on phones and required more time to upload. When I am able to increase it's stability I will more than likely use it again.
As for Apple and Android, you're going to be waiting awhile. The browser based game is probably the best you're going to get until I have a very decent chunk of the game made. Lastly, I could upload files for Mac and Linux but at this point there is barely any demand for the game at all and these formats will be pointless for now.
Thank you for your question.
