It was alright.
The game was kind of fun, though it was short and mouse click events weren't always registered. I'd like to know how rank is determined, and that's not shown anywhere in the flash.
You might try making sure that click detection works completely, add a few levels, and add a few variants and rewards for achieving a certain rank to add some spice and uniqueness to this game. Good try, though, and certainly something I wouldn't mind playing again if I was really bored.
