I really love this game - the idea of stranded StarTrek-ish crew trying to find each other on an alien planet is awesome.
I think the crew roles could be expanded. I know there is a right of veto, but the game doesn't mention much about describing the POIs, so it doesn't seem like it is a big part of the game. Maybe you can also give each role some mechanical "skill" like in board games? Not sure what they would be yet, but it is something to think about.
Also, I know that English is not your first language, but I would love to see more thematic vocabulary. I would use Scanner / Tricoder instead of Oracle, for example ("Check your tricoder readings" is much more thematic than "consult the Oracle"). Also, maybe adding more alien entries to the Oracle table?
I really like the idea behind this game, I think, if you expanded it a bit it would be an awesome game!
