Check the hose and go all the way to the highest point.

The more hoses you collect on the way, the higher you will go. The higher you climb, the more rewarded you will be at the end of the road. If you don't pay attention to the cactus, you probably won't see the end of the road. Don't forget that you did all this running to bring the trees around you back to life. You only have one mission.

The controls are pretty simple, but getting it to the highest level is definitely not easy.
