I liked this entry a lot. Sorry it took so long to rate and comment. I think it's because I played it before the rating period opened and I thought I'd already commented.
The gameplay here really captures that ninja essence of feeling super quick and deadly as you take out enemies. I tried to do a pacifist run where I made it to the end and back to the beginning without taking out any enemies. No such luck! But it shows how fun the game is that I kept coming up with new objectives.
My only recommendation is to better telegraph the enemy projectiles so the player can react better, or give me a different type of dash that can't kill an enemy, but does phase through projectiles. Just a thought.
Awesome presentation. Great juice. Excellent entry.
