yeah we have a system for height, so we can do that easily, but beyond that i dont have many ideas. im going to push for a 'solid' terrain system, so that an arrow or magic fireball can just go through things, but the problem then is that wed need a fireball pathfinding system, which would be tricky.
i dont really want to talk much about the game since this is ment to be about the pixelwork and id like to avoid this getting moved to the off-topic section
