Ending 14 has to do with the greenhouse! Make sure you've exhausted your options there; Ending 14 doesn't require anything special besides having your capacity at 2.
Ending 3 is slightly tricky to find, but it's possible you've already found it. Just pushed an update that fixed Ending 3 not appearing in the ending list when reached.
Endings in the list are grouped by the room they're found in. That may help narrow things down.
The dwarf is also a favourite of mine! Don't worry, he's plenty happy and well cared for (even if he doesn't have much choice!).
Nicely done, man. Really appreciated the sheer amount of variety. Only had a fairly quick playthrough for now, but I vaguely recall Mel reaching a bad end in one room, only to still be present when going to the next room. I'd need to play through some more, but happy to offer further feedback.
