The biggest problem I see in this type of point and click first person game is that we are all accustom to making 4 clicks right or left to turn 360 degrees or just 2 clicks right or left for a 180 degree or to be facing the direction we just came from. The problem comes in to play when the developer adds a click somewhere in the game. For example instead of 1 click moving you 90 degrees it only moves you 45 degrees. This really adds to the confusion when that extra click is when, say, you turn right in which case you need to use 3 clicks for a 180 or face the direction you came from but if instead of turning right you moved left where it only takes 2 clicks to face the direction you came from.
So if you wanted to turn around a go back the way you came and you are use to the 2 clicks right then you are off on another path...lost...when you thought you were going back the way you came. Now place yourself in this same spot later in the game your mind is messed with if you happen to go left this time. The fun really exacerbated when in another point in the game the 3 clicks are to the left not right or both directions are 3 clicks. Some games have a lot of these intersections while others only have a few. I think the ones that only have a few get us lost more because we are use to almost every intersection being 4 clicks.
Now this all being said...lets not even get into where there are sometimes intersections that take away from the 4 clicks where only one click turns you 180 degrees but watch out...turn the other way and it may be 2
Did any of this make any sense?
