I like the unique graphic assets/animations and the combo system! I also liked how all the plugin creators were tombstones, nice touch :). Not a fan of the loading times before battle, and navigating hell can be confusing at times (it is hell after all though, so understandable). An interesting premise/story, I'd like to see where this goes.
I did discover one bug too: in battle, if you go to the party menu, when you try to leave the party menu you get a "Cannot read property 'addChild' of undefined" error that crashes the game.
Overall very well done!
