Strange, I tried to boot up the game myself and it took me straight to a lose screen, it may just be me but take a look at your build and make sure your room order is right. If not, disregard of course!
Same problem here ^ Unable to play it because it brought me to the end screen directly. You might want to issue a fix, that's authorized.
Also, since this appears to have been built using Unity, you might want to check how you can get a so-called "WebGL" build. (See here) It will allow you to upload it to a website such as itch.io, so that people can play it in their browser, like our game for example. ;) I find it more user-friendly.
If not, disregard of course!
