Really like the minimalist approach :) The controls feel super tight. At first I was kind of distracted and thought I was supposed to gather as much gray blobs as possible instead of chasing the ins and outs. I would've like to see more things communicating how you're getting closer to a mindful state, maybe like some ripples appearing and going in and out as the session progresses? Wanting to see what effects show up next would give the player an additional incentive to stay alive. All in all solid entry
