I got to Bael and used my pistol on him and caused NaN damage, which then turnedhim into having NaN HP and being impossible to kill. A bug or a representation of his dark magic? Impossible to say...
Neat game, love the theming.

Thanks! There should be a message about you having to go to the next level in the forests to destroy the Totems, you then return back to the boss level to finish him off now that the totems are destroyed. I thought the message appeared when you entered his level but I'll play it a few times to see if it's a bug.
