Fun but glitchy

The game is incredibly fun. However after I got the ice wand and leave the ice temple, the game becomes glitchy. When I try to leave the swamp to return to the castle, it wont let me. When I enter underground caves, the screen turns black and I have to restart. Please fix so I can finish the game. Thanks.
