Very pretty environment art. Gameplay is a bit one-dimensional but responsive and functional. Having an ending always makes a game a lot more enjoyable, because then you know you played as much as was intended :)
The music track is well done and fits the game's theme very well in my opinion.
Oh also I loved the fishbone healthbar! 🐟 And I played with a controller, just so you didn't implement that for nothing but also because it is more pleasant to play with a controller :D
