Congrats on your first game jam! Couple of things I'd like to point out:
The level continues to generate after you've died, just something to keep in mind if you end up coming back the project. Also sometimes you can't grab the coins on the right-most side, as their rotation makes it so the player can't collide with them. (This could be fixed by maybe taking the collision off the coin, and moving it to a parented game-object, so the coin still rotates while the collision stays in place)
Other than that though great job!
