The mechanics were suprising, interesting and in-line with the theme. The 3rd door puzzle felt a bit difficult and arbitrary and I needed to read the comments here to figure it out, and then talked to the npc until it just game me the solution (nice touch). Maybe getting other people to playtest can give a better measure for tunning.
I got a bit dizzy from the camera, maybe it could move slower or something.
Really nice artstyle, visuals, and the ninja movements are sleek.
The main thing missing for me is that is too short. I think I finished it in less than a minute. If you keep working on it maybe consider adding more mechanics to be able to create more content / longer levels.
I also like that you jus respawn in your last place.
Feedback on the visuals: the background is a bit too present for me. Consider reducing contrast (as it usually happens with far away objects to get atmospheric results.
Of course there's no time to do most things in this Jam (and what you've done is a lot!), but I think you should prioritize core mechanics. The fighting feels weird, mostly because there's no visual feedback of enemies attacking or damage being made. As I player it was hard for me to figure out understanding how / when I'm getting damage and then I don't know if I should hit and run or try different tactics / make interesting decisions.
Art and sound are good. I just think it needs more playtesting and tuning!
I felt it was a bit difficult. I wish it had easier levels / bosses at first so I could get used to the controls and the game. I also ran into an issue when my target gets stuck 60% of the time (I'm playing on a touchpad - I know! :S), so maybe that didn't help either.
I couldn't find much use for the flashlight either.
It has a poem like art style and music that is chill / comforting.
Sometimes I felt like I had a hard time spacially orienting myself. I can't decided if it's something good or bad, as it also add some difficulty to the otherwise simpler game mechanic.
