This game does have tile-based movement. Just because you can't see the tiles doesn't mean they don't exist (strip it back to its polygons without textures and you're moving tile by tile, right?) Whether or not 'tile' is the official jargon for this is irrelevant - you're moving from one square/tile to the next, and have a finite number of moves you can make within that grid before they're spent.

There is no visual indicator for this that I've seen. Link to a screenshot?

When you begin to cast a spell, you can see visually see the radius of its beginning and end. I'm talking about visually seeing the same thing when you're about to move. Currently, you have keep your eye on the little AP balls at the bottom of your screen while you move the mouse out. If you think this is more intuitive/intelligent than a what I've mentioned earlier, you've failed to explain why that it is.
