Nice simple and casual game. Sadly there really weren't any sound effects. However, I noticed that the best strat was to just only spend money on the line since it can give you a lot of money per click each upgrade for a very cheap price.
An even better strat that I found was literally just getting about 2-4 circles, save up to buy a line, buy 2-3 lines, save up for a triangle, only get 2 triangles, then save up for a square.
