Porting kit works for me (for getting it set up on Mac since I doubt he's gonna add a Mac port)
The steps: Go to the site (first link under sponsored pics), go to download, download the zip file, unzip it, open it up, if it asks you about if you really wanna open it just let it open, go through the steps to get it set up that the app makes you go through and make sure to allow it to access where the game.exe file for Termina is and that the file is unzipped, go to installed under apps, add application, go to the game.exe file and open it up, don't change anything that the app has when going through the steps, wait (it takes a bit), and bam, the game is open
If it crashes without a file set up (you need to close it to get a file set up), then go through the steps from installed to the end and make sure to get your file set up
Good luck
