The game looks very nice for a closed beta and I didn't had the usual bug you expect from a game at this stage. Also the hole game concept and the ship moving mechanics seem right. So we might have a winner for the game play part.
The UI part and the ship information isn't finished especially the weapon information. How much damage does a Nav main gun do? What about the main guns of Destroyers?
There are some things that I'm not sure about. Is it some bug or I'm doing something wrong. There are some fights were it seems like you don't harm the enemy ships even if you see the hits landing on them. Here is an example, Nav vs Nav both alone shooting with the main weapon. For a long time I wasn't doing any damage to the enemy ship, shots landed on the hull but the HP remained the same and there wasn't a shield or healing.
Another example Corvette vs Corvette from full HP shooting at each other. Died while the enemy still had ~75% HP. Next fight I kill him very fast. Same things happen sometime with Destroyers or Art Cruiser, shots land and there is no effect on the target.
