Interesting I haven't encountered this bug myself (both in unity or the WebGL version)... If anyone knows why this might be the case would love to know, but thank you for your feedback
Yes I would have to agree with you, if I had more time to work on it I would have added pre defined patterns the orb would move in allowing the player to learn these and improve over time instead of just janky random movement.
But thank you very much for your feedback, appreciate it!
