Some remarks:
- no sound effect seems to come from the 2nd player
- will the whole level follow this turn around movement? or will there be some passage with simple one way scrolling?
- will the ship altitude remain the same or will some time the city appear larger?
- nice colors for the ships!

- how cooperative will the network play work? will you (for example) provide a super power if both ships join together while hiting both fire buttons for example?
Keep going this nice work!!!
