We have released an update to version 0.0.6 of the game, which includes a decrease in the progression cost multiplier from 100 to 33. Additionally, there are other upgrades available in v0.0.6. Thank you for playing and enjoying the game.

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.
