Upgrade, fight, and get rich in this sequel of idle proportions!
Gain money by stocking up on the four unique orb types (five if you can find the secret).

Special thanks to Kodiqi and Game-Icons.net for allowing me to use their intellectual property. 

Note: Reach to level 1000 to get the secret. Also, if it's lagging, just give it a sec and/or go full screen.
