Some people noticed a game breaking issue with the Windows version, and I just fixed it, it works as intended now. However, the browser version was just broken, so I removed it from the page. If you want to play a functional browser version, you can try the GXgame version, which is actually playable: https://gx.games/es/games/r4yuo1/gravity-storm/. I might add back the browser version to itch.io, for now you can always download the Windows version which is the main one.
