Ok, I managed to get about 7 work hours during the trip.
Wasted a lot of time in the wrong direction first day (programming a simple AI for the ships, and a simple 2D physics thing which won’t be used after giving some more thought).
The Combat screen (and the basic combat functionality) is going well, and the zone navigation is working already. Things look positive all in all.
Aprox. Work Time: 15:15 (8:30+3:30+3:15)
