Thanks for letting me know about the boss health after death. I guess since his health bar doesn't disappear (ran out of time to even add taht toggle). I had built in that the Slime Lord will regen his health slowly if you walk away from him (after a 15 second pause) or if you try to heal up at the job board.
Bigger picture, I'd use the extract for crafting at the very least. But yeah, I'm working on the full version of the game now. I got pumped form the positive feedback and response. Here's a little screenshot as I'm shifting the code over to have sprites for anything that animates (characters, monsters, FX, and 3D models for everything else.
