I only played for a little while but I plan to play more towards the end of the week.
I like the small additions and fixes I noticed. Ambient sound is the first thing I noticed.
Only thing that bothered me were the doors. I kept closing them on accident and stopping at them.
Good job. I will try to play more later and see the new levels and enemies.
Ps.: Could you put a list of console commands into the game folder? I would like to skip levels and cheat in exp or items to test things.
