I will start making prototype of Level_1 and Level_2. Still need to change Level_3 and Level_4 on sketch step.
In Level_3, I need to find a way to let the "fountain" can make player move in a certain direction.
In Level_4, I need to update the map. Try to add more elements about "sky".
Update Level_1, remove some useless spikes.
Try to find a method that can control the rock rolling down when player move to the slope in Level_2.
