I am really sorry. Sadly it is out of my control - the tool I use to make it, processing, requires Java 8 if you want to play it on windows. There is maybe the option to export to applets, I will look into it now!
Hi, so I think I figured it out. There was a problem in the library I used to access sound files. Anyways, I switched libraries and tested the new export on an old laptop and it seems to work. If you have time I would really appreciate it if you could give it another go!
