Fourth Challange Complete!
Harder Enemies ✓ (Some enemies are spawned with increased size; they are slower but are harder to push.) Homing Rocket Power Up ✓ (Player can launch 1 homing rocket that will chase down the nearest enemy. If that enemy is pushed out, the homing rocket will switch its target to its next closest enemy.) Smash Attack Power Up ✓ (Player Jumps using a balloon and on smash creates a shockwave that pushes the enemies hit by the shockwave.)
