I find it hard to disagree with most of the negatives but I still found it very special, and as with when I finished the Technomancer, I look forward to seeing what they do next.
My main problems with it were:
Length - SkillUp described it as a 10 hour game stretched over 30 hours, while I think the ratio is off, I see what he is saying. I had 46 hours on the clock at the end, albeit with a lot of slow-paced exploration and gathering of materials and stuff, but I think 30 would have been great.
Quest logic seemed to fall apart a bit the further you got in, reactions not making sense based on previous conversations and events. This is probably one of the toughest things to get right in a game with dialogue choices and consequences.
Romance - seems you can't get this unless you say exactly the right thing, on three occasions.
Too much travelling. I think they've had been better off having fewer, denser areas to help keep quests flowing. I also think this helps with familiarity, I can't remember half the names of the native locations and characters.
Overall though I think it's a tremendous achievement for a small studio still learning their craft. The game looks stunning at times, the atmosphere brilliant, the music was great (it always is with Deriviere) and I think it told an interesting story.
Well done Spiders, I hope it is a success.
