I really like this game! The shield mechanic is clever, and replaying the game to get the different endings made me notice and appreciate details like how the opening lines of dialog explain why Aiden's ship stalled in the asteroid field. The music and sounds were great too--they're perfect for a heart-to-heart in space.
The only thing I can think of that the game needs is a way to replay at the end so we don't have to close and reopen the game to get the different endings.
Well done on this submission! It gave me a lot to think about regarding game design.
