Spin Jump Glitches
If you can hold on to the spin jump power-up until you face Harry and Marv for the first time in Level 3, jumping into Harry simply crashes the game (Marv dies normally to the attack). This crash also occurs if you try to attack Marv by spin jumping in the following room.
Later on in the final chase bit, if you spin jump while moving into the crane to climb down (or you jump while holding down over the "secret" climbable pipe to the left of the crane) Kevin's sprites will become glitchy until you jump again.
