Wow! I didn't think see a game so similar to mine! Unfortunately (and ironically) your game isn't working for me either. Do you have a windows desktop version I could download, so that I could play your game without the browser getting in the way?

^ above is the entire console messages from my browser (FireFox) when I tried to play your game
Lastly, if the browser version isn't working, I've also put desktop versions to download for linux/macos/windows x86 and ARM
