I liked the style and the music was really fitting!
I had some trouble moving to the last stage – All the prior stages there was a light to find, but this one I just get wandering and trying to shoot the dark thoughts and after I got almost all, I got the last question to clear my mind and free myself.
I’d also suggest a rounder collider for the player next time, I got stuck on the walls a bit if I ran into them.
Great job for a first jam! Hard enough to make a game, 3D even moreso!
