hey this is pretty great! :D although just want to let you know, as this game has been recently added to cool math games (idk when precisely), it seems to be practically impossible there because the timer ticks down WAY faster for some reason, making it so it seems that only an AI could beat it.
No clue if you have any say over that, but just wanted to let you know regardless. This version doesn't have such an issue however and is great.
