To get the hard badge use Airboost and Powerswing at the tee. Then superrun after the ball has landed. All holes can be finished in two shots. Some can be a hole-in-one. Every shot adds 5 seconds to your total time. Assuming 2 shots per hole, Stony Beach has to be under 28 seconds per hole on average. Restart the hole whenever you fail to go under the 28 seconds (except if you have time to spare).
Kinda fun, when you get the hang of it. Plenty of levels also. Could be improved by blast radius, and colored dynamites (can be hard to tell them apart sometimes).
For anyone wondering how to beat the bonus level "The killing Floor". Place landmines and C4 in front of every door clockwise. Be sure to place 8 to 10 C4 on the right side of the room. Then with around 80 seconds left stay behind the boxes on the lower left screen. Whenever a guy thinks "Hey, what's behind those boxes?" you should press the detonator. Most of the time the guy will go to the sound of the blast. Else snap his neck.
Got the hard badge by doing the following: Spam green bricks in the middle until 80 bricks left. After that look for purple bricks only and spam them fast vertically on top of each other. After height 500 simple stack every brick vertically with down arrow key pressed.
