Thanks for the lengthy comment mate, do appreciate it. And yeah I get your point, looking back on it I should have spent less time messing around with terrain, and flying rocks, and more on game design. At the end its the ash cloud that is hurting you, but I didn't have time to fix the particle system to make it clear when you're inside it. Also, a last minute change the maximum camera angle makes it difficult to see the ash cloud chasing you down the volcano, as you cant look up at it. Lots of things like that could definitely be improved.
