Okay.
Art: 9/10 - Could've tried to shade a bit the characther.
Sound: 8/10 - The sounds seems fitting for the game.
Gameplay: 7/10 - Short answer? You tried. Long answer? The part with boss's jump lasted a bit too long (Like 5 secs?) plus there was no hp bar so I can't tell if I've killed him or got somehow killed (idk if not having lot of light kills you)
Note: the Myth button shows me a long text, I mean you could've worked a bit more on the text and actual make the text shorter by just trying to explain the story in 3 sentences or few. Also the light source seems a bit weird, overall, it's still good.
My overall rate: 8/10 (If you are new to coding games, 9/10, you did a good job for a beginner)
