I'll provide more in depth feedback this weekend when I have more time to play, but here are some initial thoughts:

On the Govern Planet screen, could you please add the industry and ship symbols on the slider bar (to mirror the Civilization Govern screen).

For some reason, after selecting a ship, I am having a hard time left clicking to select a destination. It can sometimes take 3-4 mouse clicks before the destination is actually selected.

In the Manufacturing Queue, the mouse wheel moves the selects up/down waaay too slowly.

Loading a saved game, instead of seeing a colony ship under construction in the starport, there was only the starting part. When the next ship queued up, it appeared normally.

Nice explosion when destroying a ship on the galaxy map.

Okay, this one could be a problem for early game play. I found a “Lost Defender” before I or the other players had weapons. I used it to destroy the starports of my nearest enemy in turn 48 and kept destroying them every time they built a new one. I know if the situation had been reversed, I would have been ♥♥♥♥ed. Oh, and I’ve found a second Lost Defender, so now I can defend my starport from the same fate.

After using an existing ship design and making a change, the ship appears as a dot in the Ships menu (same bug as Alpha 2).

When adding a sponsor to a starport, I would prefer the option to set this from the Govern Planet screen of the planet I want to add (having it there and at the Starport would be useful).

More to come this weekend, and I'll design and post some ships.
