Excellent game. I liked the atmosphere of the sewer and the textures. I'm not sure if you created the rat model or got if from a pack but up close it looks really good.

As far as things I noticed you've already noted the path finding for the characters. I found myself by myself at some very bad times. So I started constently checking to see if my party was following me. Also I'm not sure if I just missed it in the tutorial but how do you get into the inventory of a dead player? I ended up have the party member with the resurrect scroll die . It seems that the other characters should be able to access the inventory of a fallen character if they're standing over the body.

Also there were some torches on the walls casting light but had no flames. And the load game part of the sign post doesn't seem to work at the very beginning. I had to start a new game and then load my saved game. I also think that holding down the right mouse button to have a free look around hurts the game play. And I know the game isn't done but a different voice actor for each character would be good.

But I have to say great work. I can tell you put time and effort into making a good game and I think it's going to payoff for you. I was very impressed with the over all game and I look forward to it's final release!
