pls add a save feature i lost all my progress
Sorry to hear that.
The game actually saves your progress automatically. As long as you haven't cleared your browser data and you're playing on the same device and browser, you should be able to pick up right where you left off, with nothing special to do.
You can also test it yourself: start a new game, play for a few minutes, then close the game and open it again. You should pick up right where you left off. If that doesn't work for you, contact me again and we'll try to figure out what might be going on.
