Do you not know about the incremental game craze? If not, then I've got some great news for you. A couple years ago, a Frenchman named /u/orteil created Cookie Clicker, a game that was inspired by Candy Box and which itself inspired a plethora of similar games. You can learn all about them over at /r/incremental_games.
You could use a software like httrack: https://www.httrack.com/
I actually downloaded and modded the game, so you can save your progress again :D - so if you would like a working save function I would recommend downloading it from my website: http://candybox.duckdns.org
Have fun!
