An interesting idea, but very simple and you are completely at the mercy of RNG. Could be very neat if expanded upon so the player has more agency.

I guess yes, there is a lot of RNG, although you can choose which dices you want to pickup. It's kind of a choice between waiting for the perfect dice, but you and your raft slowly die or picking up as much dices, but it might not give the best results. But that also depends on the "quest" (idk what to call them, objectives?). So I guess making one of them not random anymore (follow a certain order) could be better (probably the quests).
