The major problem with this game is UI.
It's a text adventure which on the regular requires non-text or button input.
Alright time to be helpful.
Change the default scrolling speed. By default it's 1 and causes every time you hit the up/down arrows and the scroll wheel for the scrollable UI to move by 1 pixel. You'll have to mess around with it but i'd try 15 +/- 5. Missing this is just an obvious sign of sloppy Unity development.
For character creation, if you're going to force me to have names filled out, you should have a randomized option for both first and last name (if you want to be fancy, you can have race specific randomized names).
Ship based buttons need feed back. You should have 4 states of feed back [OnNormal, OnHover, OnFailedToClick, OnClick] (Not literally these names but just to give you an idea)
OnNormal is what you have right now. (Change nothing)
OnHover is when the button is selected or the mouse cursor is hovering over it. (Maybe change the highlight colors to Yellow?)
OnFailedToClick Is when the button wont proceed for some reason. (Maybe change the highlight colors to Red?)
OnClick is when you proceed. (Maybe change the highlight colors to either Blue or Green)
Also for OnFailedToClick and OnClick, you might want to add a sound effect. Please make sure to add a UI audio slider to options.
When placing your initial crew, don't even tell me there's the option to place more crew later, because with your UI i thought i could put my Chief Engineer in Engineering. You know like they do in star trek. You know that series you're riffing on. I get why you can't, just don't even tell me it's an option.
For combat..... I barely understand how that works. I think you just need to rework that entire thing. I somehow got past it but i think clicking the button on the right then selecting an officer option which are all the same? Except when they're not?
Also i dont get why the field is so large vertically. Everything should be viewable from my monitor.
Look.... I don't think you've justified a patreon with this game. I get you're dedicating your time but this needs more time in the oven, even for a WIP game.
One of the things i enjoyed about the UI is seeing examples of how I or my Officers would address each other, with real time updating. The "keep capitalization" was also a good touch.
