You have a lot of potential! I hope you like game development enough to nurture it!
This game is technically perfect, but it is so basic. Regardless...
You did a lot with a little. Good job! d(^^)
You say on the game's page you're as fresh as they come.
Given that, and the relatively short amount of time you worked with,
this is really impressive!
The music is great, it's atmospheric, but you knew that already.
However, the code, art, and feel (the most important aesthetic, in my opinion,)
are equally good.
Something you do that another novice might not is pay attention to details,
primarily regarding jumps in this case. Since you only have one animation,
having particles follow the player helps mask that. Even something as simple
as action sounds may be overlooked elsewhere, but you certainly know
how to polish a game!
Of course we'd need to see more gameplay of the hook to see how it really fares,
but right now I think it's an interesting twist that could lead to nice challenges. :)
