You are at Frostpoint? Or are you in the fourth dungeon? You should be able to get the master sword, check the village. It's always a good idea to check back in the village after you get items. You don't have the superbombs yet.
In level four, there are two floors and each warp spot warps you to the exact location on the other floor. Search for the magic boomerang, it will allow you to continue on in the level. If you have the boomerang and still are lost, check back at the beginning of the level for a crystal switch you can hit. Hope I helped, let me know if you are still stuck.
I found the sword. You have to hit the chest 3 times before it shows up. I just thought I had already gotten what was in it. Problem is, I can't get past the bottom floor. I was hoping if I hit the yellow crystal that is in among the spikes with the boomerrang, it would clear out the spikes. No dice. It didn't do anything that I can see. I can only get left, then up and part of the way back right before I die and I just keep continuing in the same place. I even tried it with F4. Then I just get hung up and have to go into the spikes to get loose.
I'm also wondering why I have the blue Bow. There is a bow in the village, but I couldn't get that one.
