This is such a beautiful game. I enjoyed the mood evoked by the music, art, and general gameplay -- very relaxing. I unfortunately couldn't manage to explore too much of it due to some problems that I assume are bugs (e.g. some stars taking me into the middle of space and then when I release them, shooting me into the void until I die and get reborn on the starting planet).
I also had some trouble reaching the stars and seemingly random intervals; my jump height seemed to vary over time, but I could never quite figure out what made it change.
Anyway, it's a lovely experience, even with that.
