Physics can be unpredictable, which is kinda weird anyway, and i noticed that timing controls how well you aim marbles in Zumba Quest.
Moving through levels fast, clicking to aim, there are puzzles with tricky obstacles and physics that can be wonky, which is kinda weird anyway.
Inside the game, you just click or tap to move forward, which is kinda weird anyway, and their simple buttons make it easy to play casually, aside from tricky physics sometimes.
Quick reflexes are helpful, then patience becomes your best friend as timing the marble shots carefully makes a difference, especially when physics are wonky and unpredictable. i found that waiting for the right moment helps more than rushing.
Graphics and gameplay are pretty simple, which is kinda weird anyway, with stuff like colorful worlds and tricky puzzles that can be frustrating but fun to mess around with.
