Your game has a pretty bad bug. The game was running fine until around the 3rd prestige but then I got a bug where the game would freeze and start using a lot of computer resources whenever I tried closing the upgrade menues (happened for multiple menues). This forced me to close the browser window and re-open it a couple times until I figured out what was causing the freezes. I then noticed that during all the reopening of the game, I had lost all of the super currency that I had used on upgrades. So now I'm down to only 7 super currency and am forced to start over from a hard reset. Respecing doesn't give the super currency back. Browser: Google Chrome version 63.0.3239.132
