Great game.  I love roguelikes, I love platformers, I've been waiting for someone to make this hybrid and it's far greater than I imagined it could be.

Most of the bugs and quibbles have been mentioned thrice over so far...

One thing I'd like to request/recommend is a more detailed high score table a la Nethack or Dungeon Crawl.  The stats so far are really minimal and it'd be nice to have a record of some of the more memorable deaths.

Also arrow traps + dark level is borderline cheese and more or less an instakill when it bounces you into a pit with a snake at the bottom.

And I'd like to emphasize the difficulties in dealing with spiders, big and small.  Their hitboxes are just so wonky, I feel cheated whenever I jump directly on top of one and fall through it, taking damage.

As for the ghost, I'm really split.  On one hand, I think the urgency it brings is great and the music when it appears is very effective in making me mad dash for the exit.  On the other hand, I feel like this game could be very enjoyable as a slower paced exploration-type game as well.

Well I'd better get back to getting executed by angry shopkeepers.

Great game, really loved the visual style and the theme.

Some nitpicks:
-Ladder travel is way too slow.
-Lots and lots of typos.
-Crashes during the credits if you fiddle with the buttons.
-Unskippable dialogue.

Still trying to go back through and beat it with no casualties
One level in particular has me stumped where a soldier shoots explosive barrels before you have a chance to tranq or manipulate him.
