Very neat concept!
I do think controlling more than one ship was a tall order in practice, and there were some mechanics that could be communicated to the player a little more explicitly. I was initially very confused why the ships would stop responding for a while after I started repairing, or if the repair was working since the ship’s “broken” texture never vanished. It also seems like there’s a threshold for refueling that isn’t listed under the command.
I uh also somehow managed to catastrophically break the game my first attempt by sinking all of the ships offscreen haha ;-; … The game didn’t seem to think the game was over, and reloading would start me partway through the map with a texture below the ships covering part of the water.
The upgrades system that dynamically added commands to your library was neat, and I do think the base concept was cool even if there were some rough spots. I also really like the UI, and the character icons were really nice! I also love that the icons had different variants depending on the state of the ship / what they were up to!
