Aww. Spoiler makes it less cool. Ah well. It's only gonna get bigger, after all.
First off, continue the assimilation. We have enough energy production now that we're in good shape for a while, and I'd like to keep that up. Continuing to assimilate large amounts of medium matter, and leaving the smooth stone alone for the moment, is a good way to continue our growth on a large scale. We're certainly damned big, after all.
I'm interested in finding a way to upgrade our core, but that can wait, for the moment, I think.
I would like to construct a couple new forms of crystal, though. Sorry.
Name: Shield Crystal (Sentinel? Armored Storage Crystal?)
Color: Light Orange, with a thick light green border surrounding it. By thick, I'm thinking two pixels; basically recolored versions of the doors.
Base crystal type: Storage
Level 0 Storage (-2.5)
Extended vision Lv.1 (1, 1 extra space)
Durability Lv. 4 (5.5, ? extra health/hardness)
Camouflage Lv. 1 (1,
)
Total cost: 5 points (2,000 energy)
Name: Support Crystal
Color: Uhhh...the only real way I can describe what I'm thinking of is 'greenish-purple'. Preferably in a pattern that sorta blends into whatever it's in, but it doesn't matter too much. Light purplish-blue, I think works just as well, and is easier on you.
Base crystal type: Refined
Durability Lv. 1 (1, ? extra health/hardness)
Conduit Lv. 2 (2.5, ?energy movement?)
Repair/Structure(?) Lv. 2 (2.5, ? extra health/regeneration to nearby crystals and/or weight capacity?)
Total cost: 9.5 points (4,750 energy)
Build Storage Crystals in the empty spaces near the surface, so that it becomes flat. Preferably, reform the Low-Q crystals touching the surface near the invincitite into storage crystals too. Turn one Refined Crystal and one Feeler Crystal into storage crystals as well, preferably, so that the two groups on the right are touching(you said they're more efficient in numbers...). The biggest hole, is, of course, the hole to the left of our core, a bit in front of the smooth stone houses or whatever. I'm mildly curious about how things are on a three dimensional scale, but that doesn't matter too much. Anyway. Next, turn all the storage crystals open to the surface into Shield Crystals. They should change their appearance to look like just more ground or whatever. Finally, reform all remaining storage crystals into high-density storage crystals. I don't know how much energy we'll have left after all this.
I would like to intersperse Support Crystals through our structure, in whatever ends up being the most efficient, hopefully pleasing(I'm not asking you to make it look pretty, I'm just hoping it does. *shrug*). Don't need an earthquake bringing everything tumbling down. Maybe a few more by the invincitite, as what I want to do next(and this may take multiple cycles, a lot of my ideas end up doing so) could damage things. I want to assimilate two additional blocks into the structure, near the core. So we can get closer and whatnot. Don't need, or have the energy, to assimilate all of it, not yet. But that will come later. Assimilating a little bit of the invincitite down near the mystery technology would be beneficial as well.
If we somehow have energy leftover, like if this went into the next cycle, put that energy towards assimilating matter, converting feeler crystals into refined crystals, and if there is miraculously something left, due to me failing to know about math in any reasonable capacity, put it towards refining Low-Q crystal. Snowballing=Good.
