level 9 is kinda crazy, gave it a couple tries but it's challenging for sure! i'm a fan of the dash mechanic you added, and i also wanna say that sprinting towards the level's endpoint with the naruto ost playing in the background is goofy and it makes me really happy, i love it
you also said that you're not good at drawing but i disagree, i think you should keep drawing your sprites and maybe even try to make some animations for the next game you make!
a couple recommendations i'd have is to make the player restart the level instead of the entire game if they die, or at least give them a few lives, just so that they can afford to make a few mistakes before restarting. there is also the audio issue someone mentioned below. you could probably also have some decorations in the background, maybe some clouds or trees or something, and it'd be cool to add some different sprites/animations for when your character is moving around, just to spice things up!
