There's actually six different endings! If you manage your crew well enough it takes a bit too long to get an ending for the proof of concept this game is though.
You can...
- Get Mutinied
- Dehydrate
- Starve to death
- Lose / Kill all your crew
- Get capsized (I don't actually think this one is trigger-able since the ship health system is borked)
- Merge all your crew together (The true ending)
