Okay 7#.
Art: 10/10 - I love the artstyle!
Sound: 10/10 - The music is good!
Gameplay: 7.5/10 - Let's start this off easily, you can infinite jump if you are touching a block. The enemies are way too op (they indeed deal a lot, bats can deal like 25-30 dmg without any defense). Also add damage buffes so you can defeat easier the enemies. (200 hp with 50 defense, mostly def from mob kills). By the time I reached to boss, the boss didn't have any attack phases which is something very important if you want to make the player enjoy the game.
Note: I cheesed the boss on first try with no problems, only two enemies was harmed during the fight.
Like others say: "Test your game before you release it"
Overall rate: 9.5/10 - I like the game and the story, but you left us with some unfinished and unbalanced stuffs.
