This is probably a remake of some known old puzzle game, but I’ve never played it and I’m not sure I got it. Is the goal to maneuver for as long as possible, to make the robots take themselves out, and then teleport and repeat? Are the door and terminal tiles on the periphery just decoration? They don’t seem to do anything.
The colors are terrible, but we all know that, for CGA it’s part of the course :) Maybe one of the alternate palette would look nicer?
