 Ashens calls the controls "painfully unresponsive" with "a lag of around half a second" between the player hitting a button and the game responding.Ashens harshly criticises a fatal glitch in the Amstrad CPC release; the game prevents the player from platforming to an upper level, instead treating it as a ceiling that the player cannot go through.This causes the second room in the game to be "impossible to complete by standard means", and Ashens notes that the only way for the player to continue is to call Tremendous Terrence, who skips the player to the next level.
