So when I read that this was not going to be in the beautiful pixel style of the original, I was disappointed. That disappointment quickly disappeared once I saw the actual environments, which are beautiful. Great light and color. I like the magic lighter too, reminds me of the mechanic of Clive Barker's Undying. I would like to see that utilized more.
I'm glad to see you expanded the weapon mechanics. The aim function didn't work as well or as often as I would have liked, but I can hardly complain as it added quite a bit to the gameplay that wasn't in the original.
The adventure game aspect was pretty good, except it really disrupted gameplay on instances where I would get stuck, for instance because a necessary object was too difficult to see (the crowbar, on my first playthrough).
The brevity of the chapter did leave me wanting, but I'm aware that this is extremely well-done and very painstakingly detailed for a flash game. The "boss" wasn't a particularly interesting fight, I just emptied my SMG into his eye a couple times and that was that. I hate to say it, but the corridor leading up to it could have perhaps been more unforgiving, and perhaps held a puzzle required to enter the main boss area (like shooting tentacles in order to get an item).
I am definitely eagerly awaiting the next chapter.
