ONCE upon a time there was a game called Jack and the Beanstalk, which for some unaccountable reason got into the Top Ten charts.
Flushed with the sudden irrational tolerance of an otherwise critical market. Thor has released the inevitable follow-up. Giant's Revenge, in which Jack the yellow blob descends into the earth for more treasure.
One mistake on his narrow route and Jack's a dead blob. That is perhaps the most annoying aspect of the game. Not only must you discover how to collect the object at the end of each screen but you must also discover the correct route, pixel by pixel, regardless of where obstacles are placed. Sometimes you can walk straight through stalagmites or monsters. Sometimes they zap you before you even touch them.
