Marble Skies features multiple increasingly difficult levels set across floating sky platforms. The levels progressively introduce new obstacles like loop-de-loops and wider gaps, so expect a solid challenge as you advance through the game.

Holding Shift gives your marble a speed boost, which is great for powering through straightaways or momentum-based sections. Use it carefully though — boosting near sharp turns or platform edges makes it much easier to roll off into the clouds.

Take your time on tight turns and near platform edges, as speed is your biggest enemy in tricky sections. Use the Space bar jump early when approaching gaps, and save the Shift boost for long open stretches where extra speed won't send you flying off the course.
