Jonbwfc Did you find any of the puzzles very difficult and did you complete the game?
Iirc, I’m part way through level ‘C’. I’ve only skipped the first ’Restricted Access", at TOM’s suggestion, as I couldn’t obtain any more power orbs at that time (a large array of them are required). I guess there’s a chance to return to that section later in the game and somehow obtain the additional orbs?
