Okay for the slayer idea... how about this... Instead of the server picking someone to be the person to slay, you could just get slayer points from normal kills. However the amount of points you would get would be determined by the kills/deaths of the person you killed. If you kill someone who has barely any kills, you don't get a point. If you kill someone who has a lot of kills and nearly the same amount of deaths, you'd get 1 point. If you kill someoned who has a large amount of kills and very few deaths, you'd get 2 or more points. Of course, something would have to be done to prevent people from using two accounts and purposely killing their other character hundreds of times to get a huge kill/death ratio and then use the other character to kill the "strong" one to get tons of free points.
I like the idea of being able to obtain certain swords and clothing through different activities. I don't think all items should be attainable directly from stores. But it's fair for everyone because even the people that don't PK at all could still buy the items off of someone that does.
I was even thinking that you could get certain items based on your AP, but I don't know how that would work out either.
The tileset is still in the works but I'm glad most of you seem to like the changes. This is only a tiny part of the overall project, so I don't want people to think I'm only making new graphics to try and show off, and that I'm not going to adjust the gameplay and add new content elsewhere.
(I also noticed there is a white pixel on the tree, but that was a simple ms paint slip, I'll fix it =P)
