I like the minimap - which is kind of necessary to do any good at all at it. I think the player's character should be at the left of the screen, which would give us more time to press the right button for movement. Also, have you thought about having the player remain in the middle by default, and return to the middle position when W or S is not pressed? The player would have to hold W or S to remain in those positions. That may fit the style of the game well.
