This week I've created two basic power-ups and a particle effect for each of them.
The first power-up is a sprint ability. After you pick it up, while moving, if you hold down left shift then the player will run faster.
The second power -up is a double jump. Once picked up, if you press the space bar to jump and then while airborne you press space again, the character will jump again, and do a slightly different jump animation also.
