Thanks for the video and the feedback.
but it still feels kind of "sandboxxy," if that makes any sense
Yeah I get what you mean. It's dispersive and unfocused, levels need to be tighter. I'm thinking of making all levels using the terrain 3d plugin I used in level 4, (Mountain alcove) that should help with both design and visual variety.
I feel the markers, one being red and the other being white, don't sufficiently make clear which one is the "turret" and which one is the mouse
The white one is the turret, the orange one is the hull weapon, the aimer is the semi-transparent white circle in third person and the (soon to be replaced) pixelated black cross in sight view. I will try making this clearer when I get around redoing the tutorial.
