Gameplay[]
If you chose the Skater in the last cutscene, this is a good practice level for him. There isn't really much difficulty, as you just have to dodge holes. It might be a good idea to avoid the crumbling tiles as well, which should be pretty easy.
If you chose the Runner, she is slower, which allows you to control her more effectively, but you will be unable to cruise across longer gaps like the Skater can. Also, it will definitely be more riskier when walking on the Crumbling tiles.
Just be careful with jumping. Time each jump carefully, so as to avoid falling. Overall, this level may trouble beginners a little.
