UPDATED VIDEO DRIVERS! Why have I never thought about that :(.

Well thanks for the info - something else to add to the fix-list.

I began playing this great game days ago, and I've seen some bugs (perhaps it's just my computer...)
-if you talk to the arena's guys from the left or the right, they disappear
-when you begin chapter 4, go back where you finished chapter 3, when you enter in the cave south of twilight castle, the event finishing the chapter 3 is replayed and you restart chapter 4
-in chapter 3, when there are two new missions in the guild, when I accepted the missions and left the room, the game froze. I reloaded and retried, and it froze when I left the room where you can eat and drink. It's strange that it was twice exactly the same bug, but it disappeared the third time I tried.

also, this game is far from being very hard, with limited money, I haven't finished it yet but I rarely used potions during most of the game but it seems to become harder near the end of chapter 3 (which is cool). And about the puzzles in Cruxen mines, I fail to see where the difficulty was, if you have already played any puzzle game once, there shouldn't be any problem because there aren't many possibilities in the cruxen mines, it was a funny part of the game. The only thing that got me blocked was the sleeping soldiers because if you walk in the square just left of the empty bed (the first bed you see), you are attacked.
Last thing, I tried submitting diver down data on gamefaqs with some comments, I don't think it will change anything but perhaps it will make this game seems more famous ^_^

they rejected it on gamefaqs, I'm not really surprised.
anyway, I finished diver down and it's one of the best game I played, thanks a lot to all who made it! the story is really amzaing...
