Lemon rain would be great to have the number increase on each successive that is clicked during the time frame... it rewards clicking the falling lemons. I found that the better trade off without this was just normal clicks because of the crit.
Also - for the world map - the bouncing icons are fun but it's still bouncing and I cant find the part of the world I havent opened in yet. This might be wrong because I have the Every Market achieve? It did become harder and harder to see.
