Completed my first run, having chosen Faela. A little confused on the ending-- I got a tape but I didn't get to leave the dungeon so *shrug*.  Is there a secret ending I've missed?  Also you run out of skill cards for level-ups eventually, which is a bit unfortunate.  Game was fun overall; never did figure out how to sell things.

Nice! There should be a VHS tape that plays a ending. To explore more of the story of the depths as a whole its best to play more, Zorg next would be best. 

Most secrets are held within the collectables.
