Why don't you try to make dollars drawing some lines to follow?

And second after second dollars become more and more distants, so speed becomes usefull.

Your upgrades are really too expensive:

for $300 you just makes appearing red $5..

After 15minutes of playing I stop and I find it boring...

Draws dollar lines, some bonus (it's just mathematics, if you complete dollars lines you multiply gains by 1.2 or more, it could add news upgrades).

If you can, try to find a more beautiful skin for the background, we see too much pixels of clouds.

So I jut give you 2,5 stars as a neutral position!
