I think it would be OK to fix the game crashing when you die, as it does make restarting after a death frustrating and unappealing. Those sharks were scary. When I finally got my boat I was like "HA! Forget you, sharks!".

Thank you for the feedback. I managed to fix the crash on death bug.

I got the crash on death bug. Could the weird lines be caused by numerical instability? implicit casts from doubles to ints or something? Liked the concept though, quite minecraft-y

It was a ok game, but the lack of instructions/history/objedctives put me down a bit early on (didn't knew what to do early on, didn't knew how to "craft things", etc). While most of the sounds were quiet, the "death" sound was really loud and spammy.

I wasnt sure what to do and the game shut down when I died

Not bad at all; It would have been nice to have a health bar (unless I didn't notice it...) and some sort of directive as to when to expect certain items to become available would have helped the pacing.
The sharks were a pain in the butt and I suspect that they sapped a good 90% of my health before I was pack raped by a group of three or four trolls.
Kudos for getting ambitious with your entry, and good job getting it done in under 2 days.

My play time consisted of knocking down about 40 trees, beating on the same rock for over 2 minutes, making a boat, and then getting RED SCREEN OF DEATH'D by a water-skipping zombie troll. Not sure how to actually get stuff other than wood. I also found no way to hit the troll after the screen turned red, as I became frozen and he mauled me endlessly. :(

Nice game.
As they said, Morw instructions! More items!
It can be a great game!
