Game or tech demo, this was neat! I did eventually work out what I was doing with the tank controls enough to get the transponders to the door (using the back of the arrow as a scoop and backing up), only to realize upon pinging that the goal was in fact to arrange their *distances* from the door appropriately, which would have been slightly easier... I would probably not have the skill-or-else-patience to play a full game of this, but I definitely dig the concept, the music, and yes the graphics. (The graphics are minimalist but that means they don't get in their own way.)
