What I got to play was pretty great, like other people said, the windows version is not working so hopefully you can figure it out later.
I am garbage at monkey ball but I had fun with this, played probably the hardest level first lol, sadly I couldnt finish the game because it frozes for me on browser sometimes and I have to start from the beginning, also there was this one letter that requires you to jump over a portal, but even if it visually seemed like I didnt touch the portal at all, it would always send me to the level.
