On day 2 I felt kind of terrible, so I didn't do much except add a climbing animation for the ladder.
Today however I added some basic enemies, they do not yet patrol but some basic left/right patrolling movement is planned.
They react to sounds, if you make noise they will go to the noise source, however only horizontally as they do not climb ladders.
If you are in their line of sight they will also move towards that source of whatever they see, and when in a certain range of the player, will open fire.
When you sneak behind an enemy you will get the option to eliminate them by pressing E. Right now it just plays the animation and doesn't do anything else.
Most people seem to be putting in a lot of effort and time into their projects, however I'm feeling not so great and I think I'll have to drop the "chain reactions" theme altogether and just focus on the assassination part.
