Tutorial question

[crashkid]

Tutorial says to "Upgrade Mecha, and unlock [Mecha Flight]"

Under upgrades I see 5 levels of "Mecha Core" but nothing saying just "Mecha" and I don't see anything anywhere related to Mecha Flight.

The upgrade you need for basic flight is 'Drive Engine' level 1 [Note: Requires already unlocking 'Mecha Core' level 1].
(for interplanetary flight you need 'Drive Engine' level 2 [Note: Requires already unlocking 'Mecha Core' level 2])

I think the "Upgrade Mecha" was just generally pointing you towards the upgrade page of the tech tree; rather than trying to tell you the name of the upgrade(s) you should pursue.
