I made the game in 7 days for VimJam, I wish I had more time as it's pretty rough in some places. When the voting is over and I can edit the submission I will do something about the 1 enemy exploit.
I think you encountered a bug... The ship is supposed to land on earth and a little message saying the rescue mission was a success should come up. It's not the most exhilarating thing, but I made the ending on the last day of the jam 😂
Thanks for taking the time to play my game, I really appreciate it.
