Balancing feels very off, you get okay progress for the first 2 “prestiges”, and then on the 3rd one it takes forever! I went from playing actively, to going idle for hours.

Instead of forcing an update every frame, you can instead use requestAnimationFrame(), and then calculate the fps to get your delta time for updating the game. I see that the game is minified and obfuscated so I can’t see how you do things, so I’m afraid I can’t help much more with this.
