Stage 3 is fun, but the random early poking around in Fractured Void feels tedious for no reason. Even with the 6 million light caches, if you mess those up you're pretty much softlocked until you happen to figure out where the new constellations can be found.
This seems pretty cool. Maybe add a way to see the trajectory of an individual marble so its easier to see how they react to adding blocks? Also the vertical boosters feel redundant in comparison to the speed boosters (unless I'm missing something).
Maybe there could be a third automation setting that maximizes the lowest tier of color before moving on to the next one? Because the normal options don't really mesh well with purity
I think what really sells it for me is the fact that the weirdness of doing both of the main routes is acknowledged. I'm excited to see where it all goes.
