Stuck

Can't get lighthouse focused on tombstone. Walkthrough directions on control RLURD not not working. Help.

the code is different in every game. You need to go to the graveyard and find the 5-digit code on the tombstone, then go back to the top of the lighthouse and click R for 1, D for 2, L for 3 and U for 4. So if your code is 12344, for example, you click RDLUU.
