Final chapter of Penumbra

Hi, don't know how many of you are playing or have played Penumbra Necrologue but I realized today there is a final chapter that goes along with the game on Steam at no charge. I started on it tonight and oh my,hope I can finish it. The name of the final chapter is Penumbra: Twilight of the Archaic.
Enjoy,
Terri

Thanks, Terri, and have fun

I must ask if anyone is playing this game. I'm pretty sure I'm close to the end and have come to a place of difficulty and am wondering if it can be done with the keyboard and mouse or if it's going to take a game controller/pad. I've been saying I'm going to buy one and haven't done so as of yet. I'm in the underground tunnels with the giant worm and need to unblock a door.
This game is so good just like it's predecessor.

Thanks.

I see there has been a lot of peeks on the Penumbra (Twilight of the Archaic) post. Is anyone playing this game and has anyone gotten to the end of it using the keyboard?

I hope so, Terri
