just replayed it (and noticed the use of negative space and I love it even more now). It's the 4th checkpoint - after the 4 balls fall down, it always resets to the 4 balls
Hmm, to be honest, it's actually working as intended with the checkpoints. But I do realise how that particular one is confusing.
huh, I expected it to give you a checkpoint where it says "checkpoint" lol
