I've released a minor update to IDM! PNE with a few fixes and balance changes. Here are the patch notes:

1.0.1:

 
- Changed instances of "attack speed" to "action speed".
- Raised the MP cost of Recover to 30 MP.
- Removed action speed penalty from Inferno, Icicle Rain, Tornado, and Quake.
- Made an addition to Bulwark's description noting its increased action speed.
- Fixed an issue in which Chill status wasn't lowering some of bosses' ailment resistances.
- Fixed a passage issue with Lieselotte's home.
- Fixed an issue with Analyze Scroll's behavior when used on Mimic.
- Corrected inaccuracies in certain enemies' Analyze Scroll information.

I've also uploaded a PDF that contains various information related to the game, such as maps and enemy behaviors, and elucidates some of the game's more obscure aspects. I guess it isn't a guide in the sense that it doesn't explicitly tell you, "Go here, do this, use this strategy," but I think a guide like that would run counter to what I wanted to do with this game. It should be a helpful companion nonetheless.
