The game mechanic is really interesting! Flying around and clicking on the spheres makes me feel like I'm very skilled.
It was a bit confusing to figure out how the game worked at the start, though. Maybe something like the lore computers (which were also really neat!) at the start could help explain things?
Personally, I also feel like the hitbox for the spheres was a bit too small which felt a little unfair at times (or I'm just bad at aiming).
Other than that, the ending segment was awesome! The platforms were a bit hard to see, but the sudden contrast is very memorable and the weird atmosphere makes it feel tense.
