Hey, this is a very cool game! I'm impressed by the sheer amount of content! The artstyle works really well with the low resolution and the horror theme, and the level layouts are pretty clever. I really liked the mysterious atmosphere. It's cool that you can take several paths through the levels. However, I didn't get to the end (yet) because I kept getting lost in the city level. Overall great job, this is very promising!

I ran into a few minor few issues, so I'll just list them in case it helps:

• The font is difficult to read because of the anti-aliasing (I think you can turn that off in godot)
• The scanner always seems to keep the last message, which can be irritating sometimes
• There is a pit near the orange syringe that I got stuck in several times
• I managed to fall out of bounds at the beginning by jumping over the fence
• After picking up the orange ammo (that says "exp"), when I cycled through ammo types it wasn't there (only "def" and "shk")

What Software did you use to make the levels? They're huge considering the time constraints.

reminds me of a voxelworld kinda! Nice use of darkness!

This is slick.  I was going to comment about the text, but you already did.  I love the scanning, and overall it drips atmosphere.  I really like the work you did within the constraints, I hope you continue to work on it.
