I appear to become invincible after dying. I died in the final phase, hit retry, and the boss just couldn't damage me anymore. I'm not sure what happened there. Maybe the player's hitbox didn't activate properly? I would consider the player and boss being a different color from the background, but the way it is now isn't too bad. Also, I have to agree that the boss feels pretty spongey and could do with a slight nerf to his health. Still, I liked it for what it is. Good work

I liked the game! For some reason I couldn't do a sword swing in the air, which may have been intentional but it was still strange. I thought the boss could have a little less health, by the end of it it felt super spongey and just devolved into me running away and throwing shurikens at it over and over. Still, the visual style of the game is awesome, the pixel art is great, and the sounds aren't bad! Pretty fun little boss battle!

Nice game

but the boss could be another colour like green
