Godot looks great, but I want to separate game logic and display. (self.godot)

I like most things I see about Godot, and I'm going to try making some games with it.

Whenever I imagine programming a game though, I imagine the game logic and simulation being separate from the display. For instance, if I was to make a game like FTL, I would plan to simulate all the ship interactions and the movement of the characters purely in code, and then write a separate module to render that simulation. The simulation could be rendered with graphics, or with text, or whatever (of course, a text render wouldn't be human friendly, but could act as a dedicated server for some games, or I could use it for machine learning, etc).

I'm not an expert at Godot, but it seems this mindset is not going to fit well into Godot. Is this correct? It seems like the same object that is responsible for tracking the players health is going to also be responsible for drawing that player on the screen and tracking their location on the screen, etc. Will my player class have to end up being a subclass of some complicated Godot class? (Also, I'm a fan of functional programming and don't always use a lot of classes if given the choice.)

What are your thoughts about this. Would you recommend another engine? No other engine seem to be in the same sweet spot that Godot is currently in.

FRP is interesting. I could connect a FRP system to Godot's rendering server, as suggested in another comment.

Also, I think there is push-based and pull-based FRP. Pull-based would probably work better, the FRP updates would only calculate as new values are pulled out of the system by the surrounding Godot code.

Overall though, FRP seems like overkill (I'll still consider it), but its moving into building-an-engine territory rather than building-a-game.
