Everything was polished amazingly! The combat was super smooth, the design is really good especially with the synergies of throwing your sword and dodging to control more space is really fun to pull off. The boss fight was definitely a treat and the art style looked really fun. But the best part about thsi game is that damn music! Take it away and its just your average dungeon crawler but with the super hype music it made me wanna do things man!
My huge complaint however would be how this game matches with the theme. It was rather one dimensional, how you HAVE TO sacrifice one of your guys just to enter the next level and it just makes me wonder why cant I just kill them from the start?
Overall as a game, it is really polished kudos my friend! As a game about "death as a new beginning" I think it could be explored some more.
