Finished this last night. Enjoyed it a lot. Even if it is VERY hard/frustrating in places.
I also finished this a few days back, absolutely loved it. One of the best games I've played in recent years. It took about 10 hours to finish in total.
Here's hoping they make some more.
Is this just a single player affair?
Which unstable ground bridge? I'm trying to escape from something that's after the bit with the rising water (but similar thing) and it's stupidly hard.
