Awesome game!
Though I'd like to report a problem with Safari browser (ver. 16.5.1) on macOS Monterey.
On level 10 the mouse cursor disappears. It can become visible after clicking the menu button, but the frogs remain unresponsive to mouse. Also restarting that level hangs the game.
Had to replay the game from scratch in Chrome, but it was very worth it. My girlfriend loved the game too!
