This is level 9 of the Box Storage Area.
In this level, if you use the Runner, you need to know where you need to jump. If you need to jump farther, then use the high jump. If not, please use small hops. Sometimes, there are crumbling tiles. No need to feel afraid of them, and when you step on them, you don't have to immediately jump away from them. It takes some time for the tile to completely crumble, so don't panic.
The ice ramps can't bring you too far or high even if you run on them, so make sure that when you want to jump, don't just run on a ramp. Instead, jump on it.
