in 1985 Palace Software came out with a game called Cauldron for homecomputers like the C64, Spectrum and CPC.
the main character was a witch on a broom who had to collect magical items and bring them home to brew a mighty potion together, to destroy an evil Pumpkin and finish the game by doing that.
But..he is back..and seeks for revenge.
one year later, Palace brought out the game: Cauldron 2 – The Pumpkin strikes back
the game starts at a random spot where we have to navigate our always bouncing Pumpkin,
collect items in a given order and in the end to destroy the witch in her own castle.
This very good flash adaption of that game convinced the gamer´s heart as it is really close to the original. not to forget, a good game for coming halloween 
I know my son will love it.
