I bought the game 2 days ago, and completed it in about 7 and a half hours on easy (not complete 100% but I got to the end of the story)
That said, it was very enjoyable along the way, and in my opinion will have been well worth the £24 I spent on it. (ASDA = win at the moment for game prices)
I do regret however, starting on easy mode... The second file I just started I decided to skip the normal difficulty and go straight ahead to "deadly", this is where the title of the thread comes in.
The first chapter alone took me a good deal longer on this difficulty setting than it did originally, despite me knowing the area better now, it really is properly difficult. With a fiendishly unforgiving amount of life where some enemies that barely made a dent in you for easy, can now defend themselves much better and kill you in about 5 hits.... I would almost call it Zack & Wiki level of unforgiving-ness (yes I know, not a real word)
Case in point, the first major enemy you meet is (Spoiler) a rattle-snake, which was actually relatively tough on easy, as it was one of the few times I died (about 15 times in total for easy-diff, about 5 of which were just from falling off from high up) Now on "deadly" I died 5 times, even though this time I knew what I was doing.... not too much later on you meet a pair of white beetles, which on easy I didn't really notice they were a major enemy, but their defence reactions seemed very enhanced, and at that point you don't have access to any decent attack power so going in head on ultimately leads to your demise, instead it makes you think tactically. That was a further 5 deaths I believe.... and 2 more against another white beatle and then against the scorpion
So far, on Chapter 1 on "deadly" I have died almost as many times as I did in all 10 chapters on easy.... more if you take out the 5 deaths from falling which will likely not be repeated.
Basically this thread is about my advice to future buyers.... When you start the game, if you are up for a challenge and don't get over-frustrated at the unforgiving parts. Start it on "deadly" difficulty. If you are not, then start it on normal difficulty (I haven't tried this one yet myself though) I would leave easy difficulty unless you have a young child interested in insects.
