I was in the zone last night playing this and managed to get to level 16 (you know......16 igloos)
Is it even possible to get to the 21st igloo? Is there any special type of graphic acknowledging such a feat? Or does it just reflect one single igloo as the 21st level? Work with me here, I still want to believe that there are numerous undiscovered Easter eggs in these old game cartridges!
In these higher levels the seal is on you like a laser and those damn penguins are moving and twirling so fast that my hats off to anyone who can achieve igloo 17 and beyond.
