Thanks Paspartout, I sure will check out your game too. I think my upgrading system isn't very clear. It is the way Konami in the old days did it. When you pickup an upgrade, it starts with upgrade 1 (speed) and with every pickup it goes to the next upgrade. So blaster is more expensive than speed and mirror is more expensive than missile etc. When you 'buy' an upgrade, it resets to zero pickups... Thanks for playing
