Today we added line of sight, path finding, new tiles, guard AI and skills. Guards can be patrolling, standing in one spot, or sleeping. There is a gray question mark above the guard when there is a possibility, that the guard can see you. Yellow question mark means that the guard is suspicious and will investigate. Red exclamation point means alert. Civilians will have the same states, but they will run get to guards when in alert state, instead of chasing the player. We started working on inventory and equipment, but those are still unfinished.
During day 5 we will probably finish inventory and start working on combat and stealth mechanics.
