This game... my gawd, for the first 30 seconds I was hooked, I was like "Man, this is the greatest thing to ever come across my eyes", I kept clicking that chest and then realised at the top left corner there was an upgrade button. I clicked it and to my surprise I could increase the rate I picked up gold. I immediately acquired the upgrade and watched as my income doubled, I was so happy. I really enjoyed this game the only downside is the single sound effect is way too loud and should sound like "cha ching" and the background is a bit dull. WHEN IS THE SEQUEL?
