Ok, but some major problems...
I will admit i haven't watched episode 1 and 2 but just watching this I found some major problems you should work on:
1) Get rid of the random german. It doesn't make any freaking sense.
2) Triple check for spelling and grammar errors. There were quite a few. If you have to copy paste your text into microsoft word, do it.
3) Some of the characters didn't makelogical decisions. Deciding to tell a very long story when you are rushing to save your friend wouldn't be something I'd do. Also walking off to get resources because you are bored with your friend being knocked out on the beach isn't a very good idea either.
Overall it was ok, but the above things need to be fixed.
