Nice game! especially considering it was done in 48 hours! very impressive, well done!
I encountered the same bug as the other guy (Memory allocation failed) while holding 'a' and holding the left mouse button down aimed at the center of my ship. about 8 chain guns, 4 rockets, a laser, 10 thrusters.
I was a bit confused that we couldn't add other stuff onto wings/hull once we attached it to our main hull, but I dunno if that would break the game balance.
