The game has chill music and satisfying sound effects when you shatter crystal and glass objects. Sometimes the game speeds up and throws obstacles in your path with only split-second warning. Another aspect that increases the challenge is that when you fire a ball, it doesn't fly in a straight line; it flies in an arc and is affected by gravity. The game gets difficult pretty quickly; there are about a dozen checkpoints and I'm satisfied with having reached checkpoint 4. But there are other modes like zen (endless mode, can't lose), training (reduced difficulty), mayhem (boss challenge), and local multiplayer versus or co-op.
I bet it's an even tripper experience in VR.
