Simple concept but a reasonable one; collect bullets and throw them at invading walruses before they eat all your ice. The bullets are actually curry, rather weirdly — do penguins particularly like curry? do walruses particularly not like it? — but the main problem here is that the walruses appear and then disappear waaaaaay too quickly. Either you need the reflexes of a particularly quick-moving cobra to play this, or I’m doing something wrong, because I hardly ever managed to get into position and actually hit one of the attackers before they vanished again, which puts the game too far into the “frustrating rather than fun” category. Nice idea, though; it’s quite reminiscent of the sorts of 8-bit games you actually got in the 80s.
