A few things, first clothing kinda usless with no visuals. You could make clothing more functional though, like workout clothes give increased training, and the higher tiered clothing for upgraded jobs give increased effectiveness at that job n such.
Disagree about it being useless with no visuals, it still adds flavor. Doesn't offer much (if any) impact to the game though (aside from being a silver sink), definitely agree that clothing would be improved by passive effects, or making the benefits a bit more obvious if they already exist.
Second I strongly recommend agenst a forced end after main story is finished. For your patreons you should include side patreons only storylines and give them early access to content. This way the base game itself isnt a huge turnoff to non patreons who might eventually be patreons.
Patreon only content is tricky, there are plenty of people who will flat out refuse to support dev's that restrict content like that. Typically the best option seems to be patreons getting access 2 weeks or 1 month ahead of the public, it's a fairly decent mix of giving the patreons a benefit and not annoying those who who would support, but have dealt with enough scummy dev's to be opinionated about reward policies (for clarity, that's NOT intended as a jab at Novus or anything of that sort). Also is probably the best setup to attract free users (a.k.a. perspective patreons) aside from the tip jar style (which most new dev's are skeptical of, and admittedly works better for proven devs).
Lastly, the lack of any graphics in a game really limits your potential player base. Even portraits or ragdoll graphics of your characters would suffice, acually leaving it to people to upload there own pic for this could in turn be as good if not better for base graphics with the option of player uploaded graphics. (And to clarify when I say uploaded I mean player selects pic file on there pc for it)
Paperdolls (ragdoll usually describes physics handling) would probably be the way to go if Novus was interested, given that the player can modify the bodies of it's followers. A tag based system could work as well, but runs the risk of leaving the player with 2 very different pics after a fairly minor change. A lot of people actually are fine with text only, but it wouldn't hurt to have the option to use one of those methods, as long as it doesn't take a massive amount of time to implement.

Just warning you, if you have a locked cheat menu like that, you're going to have people messing around with your code and posting mods that re-enable it when the game gets a bit bigger. Even if you fully strip it from the free version, it'll get pulled from a patreon version or an alternate menu will be developed. Your call on how you want to handle that, but figured I'd make sure you were aware that it will almost definitely happen so you can figure out what you want to do.
