The game itself is pretty good for a solo dev. The music is great, but I would've liked to hear a more mystical theme to make it fit more with the visuals of the game itself. In terms of sound design, it is alright, but there could've been a more natural sound that uses a grinding sound of rocks to better suit the boss. However, the animations are great and I love the overall design and aesthetics of the game. The gameplay is fairly challenging, although more variety in map design could be used to better leverage the movement of the player. Putting more platforms across the stage and having more movement options to counter the boss's attacks would make the game much more dynamic and interesting. Overall, a good start to a game! I can see potential in your games in the future!
