Great work! I really enjoyed the gameplay which reminds me of FTL, which is one of the games in which I put the most hours :D
I journeyed to Ganymede without too much trouble, though I did have some time with hull or nav with over 50% damage, so I had to pay attention. I tried to maximize level gain in different modules like I'd do in FTL, to have a well-rounded crew that can handle any threat (always 2 crew members with some skill in the area that needs attention).
The music was OK for a couple minutes but eventually I found that it didn't really match the game's atmosphere, so I muted it.
