Finally beat it
Although the button mashing and constant barrage of enemies gets tedious after a while, it was fun seeing all the custom death animations. Also I noticed if you slash at a female enemy it cuts her shirt off, but if you throw a ninja star it gets embedded in her heart. Do all enemies have separate death animations for getting killed by each weapon? Just wondering.
Again, fun game. Killed some time, and I obtained Master Samurai. Keep improving.
