Personally, I'm not a fan of this genre, never found them very engaging, just so you know where Im coming from. With that said, its very well done for what it is, and feels very ambitious for a short jam (you even have factions!). It's well presented and has fitting sounds.
Really like that you could drag your paths as you wanted to, adds a great feeling of control then if the ships would have been going in strait lines, also like the in-between ship-fights etc. Adds to the feel of it.
As the gameplay itself is not my thing I wont comment on it that much (it is, what it is), but what I would have liked to see is a bit more details to heighten the space "feel". The planets felt very static for example, maybe add a bit of rotation/movement there? You already have the selection effect of the planets so would love to see more of that type of stuff. Maybe the planets could have been more varied? Having one being a giant space-station etc.
Overall, great work.
