Amazing quality and sheer content load.
The biggest issue seems to be there is no hints or guide. I can not find out how to beat xxxl25 in floor 5, nor find out how to beat akane in floor 6, nor figure out where to get wood for floor 7. Usually games of this complexity have some sort of help like youtube walkthroughs or a pdf guide (covering more than the beginning) but until it has it, it's not fully playable.
