Managed to get the Good Ending.
I liked the cold, oppressive atmosphere you created and I'm fascinated by anything Soviet-related so that's also a plus.
Like others have said, I had a hard time following the story. I'd suggest including more notes to help flesh out what's happening. I just had to guess at the plot and I probably wasn't correct.
You've said you "lightened" up the game but jeez man-- it's still super dark. Too dark to see half the time. Maybe a flashlight or something?
I did enjoy this however, and I think you've shown a lot of potential here. Keep at it and the next one will be even better I'm sure. Cheers.
