Yes, sorry for that, I need to update it. The thing is that, because of the servers being down, I could upload the game but I couldn't test it to see if it worked (and it's my first time uploading a game as webgl). Hope you still want to play the game :)
I have updated it. The only solution I could come up with is to make it always fullscreen. Anyways, it shows two blue bars that shouldn't be seen when playing.
