Hi,
the idea behind the game is very cool, I think I haven't seen a game like that yet. The problem is that it's not executed in the right way: first the player can see the character, after which the die and they can see the map. The problem is that it's very hard to keep in mind how to traverse the level while also having to keep in mind the 'imaginary' position of the player, so maybe you could give the player feedback on where he is (a little cloud when the player lands from a jump or an 'image' of the players current position every 5 seconds).
The player controller itself was also quite janky (I think you've used a rigidbody for this, but you could try looking into transform.Translate: this works good for 2D platformers that require a lot of precision in input) and maybe just have the jumping be a constant strenght, but that's personal preference at this point.
PS: I'm impressed by the amount of time you guys had before the deadline :)
