As an older person who enjoys playing the game why have you time limited the game to just 20 seconds? I understand that originally it was 45 seconds, if so why reduce it by over 50%? I know that extra seconds appear randomly and that there are ones that are already on the board but these are heavily protected you cannot readily access them. 20 seconds to achieve 50,000 points - that averages out at 2,500 a second!!!Make levels difficult but not impossible.
