I loved it! This game made me feel some emotions. The music was well suited. The theme and limitation were strong. I enjoyed the return journey even more than the outward journey, and I found the end very satisfying.
I'd have liked maybe one or two instances of branching, so I felt like I had a bit more agency over the storyline (but the same could be said of my own game's narrative). Also, the movement was a bit jumpy, which went against the smooth and dreamlike atmosphere of the game, but it wasn't a big problem.
Overall, very touching, enjoyable and memorable :) Thanks!
