Hello SuperPowerJoe,
first of all: NO, there is no real reason. But in the past I did a lot of retro games and most people who played them didn?t like the key movement, so I decided to use Mouse Movement and Pathfinding for this Game...
But I see/know your point of view, there is another game I am working on (A kind of Boulder Dash/Emerald Mine) and there I implemented Keymovement and thats real cool for that kind of game.
Have a nice day and thanks for testing...
Stefan
P.S. Sorry for my poor english, I am from germany^^
