Great game, and to be honest I had forgetten all abou the menu items until I beat "the game". It was a very interesting one and I fully enjoyed it.
The only graphics I actually liked were the first one with no upgrades and the final one. Hmm, just a matter of opinion though.
5/5 with 1,747 seconds played.
The only thing I don't like abou the game is how the money orbs and power ups drift off to the left. You lose them if you kill enemies too far up on the screen.
