Interesting game. I think it needs a little more hand holding at the start, just a bit - I didn't really figure it out till I read PedroFih's comment below.
Found a likely bug:
When I reach The Orb (options: 'Attempt communication with The Orb' or 'Destroy The Orb') I keep doing 'Build Keystone' and it doesn't make any significant difference to travel time. The last 3 times I've done it I've repeated my exact actions and arrive within much less than 1 second of the last time (when travel is about 48 seconds, so 10% should speed it up by about 4-5 seconds).
Process: start with Beta, Gamma, Delta, Zeta, Zeta, Zeta; put First Formation on Propulsion, then put Beta, Gamma, Delta into Propulsion, so it hits x20.83; then Propulse, Approach the Glow, then (time now 86.93/87.75) Approach The Orb, arrive 25.35/87.75.
Test: after the above, put First Formation on Ether Gathering, then click Build Keystone, then Gather Essence to get a Beta and Gamma, then Begin Again. Build a Delta with the Spinforge (so I don't boost Propulse), then Meditate until Begin Again, then follow the above process again. Propulse still starts at x20.83 (same), start final step at 86.93/87.75 (same), arrive 25.21/87.75 - change is 0.14 seconds, not the 4-5 seconds expected, and that change probably came from Ether Gathering getting polished by Build Keystone, Gather Essence, Meditate etc..
Also: I suggest an 'end run' button for when we've done what we want to get done.
