I've a tip for anyone starting out in this game. As soon as you've completed the initial things, such as obtaining your pet and getting the stick and have entered the first area of Castaway Beach, here's what you do to get a somewhat easy start.
1. ) Do not start any quests before entering, and do not stop to complete any.
2. ) Gather up 28 of the Beetle Shell items(This will take a while, but I assure you the loot is profitable) In doing so you will most likely as I did end up with a little over a 100 Gold, about 10-15 beetle eggs, 40-50 Berries, and a lot of Fire Shards(Save these!)
3. ) After doing so you should be fit to fight off some of the snakes, do this till you have 5 snake leathers.
4. ) You should now be around level 5-6 and should easily be able to pick up every quest for Castaway Beach at once, do this and complete the ones you have the items for, kill whatever needs killing and activate the Generator.
This is what I have for now(I haven't gotten further on my second playthrough yet, I'll update whenever)
