It's great! It's like Portal with hookshots. I do love myself a good hookshot.
Some great level design, and it's packed with content for a game jam game. Very fun, and great execution.
You should specify what your idea was, so we know what part was supposed to fit the theme. In the meantime I'll guess the theme was Only a shot per jump, which is a weird way to fit the theme.
Original idea (as you said, apart from us), and a good one at that.
Yeah, the orignal idea was a sort of puzzle-dungeon like Zelda but what if your only weapon, a bow, only had one arrow.
So, then I thought instead of picking up the arrow every time, what if you had a rope/chain attach to it to pull it back out of enemies.
And then I thought, what if you used that idea/mechanic as a utility item and to solve puzzles/hit switches, move around the room, etc
And then it became this, a platformer:)
Mainly because I didn't have the time to model and program enemies. xD
I admit, I strayed a bit from my original theme idea but I still had a blast making it.
