Gameplay Changes

What's new and why it’s needed:

1. I changed the shooting mechanics, which added more dynamics to the combat. These are not the final changes to the weapons; the impact of shooting will be further adjusted in the coming days.
2. Blocks that were blocking the passage have been replaced with radioactive fields. They lower HP but do not obstruct the passage. This way, I maintained the principle of "consequences" but eliminated the issue of complete blockage of the passage, which was frustrating.
3. Added blood stains on the floor and effects when lockers fall.
4. Added HP reduction indication through desaturation.
5. Improved ambient sounds.
6. Added some props.
