Recently I played, beat and really enjoyed this quest.
I thank the author very much for your great and wonderful work!!
By the way I couldn't get the master sword because of lack of
only heart container pieces.
These are what I found:
1. in front of entrance of Sanctuary
2. in the bush in H.Meadows, near the west end of the bridge
3. at the west of Armoses in Alien Ruins
4. in the bush in front of entrance of Sanctuary
5. on the rooftop of Mega Mart (Lv2)
6. by the pond at the east of entrance of Neon Park
7. at the northmost of Neon Park, beyond the pond
8. on the other side of the river in Alfheim
9. on the rooftop of Lv6
10. by the entrance of King's Tomb
11. in Nexus through the secret path from The Bone Zone
12. in the bush in Land of Sorrow, through the secret path from TBZ
13. near the switch in L.of Sorrow, through the secret path from TBZ
14. behind the boat in H.Meadows
15. under the water in Mario Clone Bros
I appreciate any help to find the last one!
Thanks in advance.
