It's a pretty interesting take on the theme. I like the ninja sprites and all of the animations seem to be decently fluid for enemies and player alike, so good there. The sprites of the ninja seem to be inconsistent in size, though. When you attack, dash, or jump, you kinda shrink down before enlarging back to your normal size for idle and run. Makes the player look a little wonky when that happens. It was kinda fun to play around with trying to be as strong as possible to see how much I could get away with, but it was hard to tell when I was making a successful attack on enemies sometimes. Some seemed to die in three hits, others in 6 and I couldn't tell you why. I eventually died to some robed guys and got locked out of the room when I respawned, unable to proceed further beyond there if there was in fact more. I think the door might need to be re-opened on player death so that people can go back and try again without having to play through the whole game a second time just to have another crack at it. Still, good work on releasing a game! The concept is pretty neat.
