Nice multitasking game. I couldn't figure out how to fix the hull. I accidentally fixed one hole by pressing F near it but I couldn't get it work after that again :DI got to around 600m by defending since I didn't know how to fix stuff :D
Well, you use space to hammer stuff around :P That's my tip for you. Still impressive as hell that you manage to get to 600 m without fixing stuff. Thank you for playing.
