Aside from full-screen being aligned to the top of the screen for some reason, the visuals are incredible.
I also initially liked the gameplay, but after I died due to stress, I realised that stressed increases with movement and by hitting obstacles, and stress reduces by waiting...
And the wait is really slow.
I think instead of stress killing you, it could instead just affect how fast the ball spins, and lives are a separate mechanic, like a simple '3 lives' system.
I will say that it is challenging though, though I stopped at level 3 due to needing precision to get through the narrow corridor, and built-up stress meant having to wait long for it to go back down to get my precision back.
Overall, great game with incredible visuals. Just some tweaks with the stress system and this would be amazing!
