No visible functionality, no basic mechanics for game to work with, no instructions => no game. Currently it is just a confusing bunch of concepts and ideas thrown together.

Only two keys seem to do anything: "L" induces shifts, which might look like resets, but they do not really reset everything: green tanks may disappear or appear in a different location or stay where they are, shots may stop or may just keep coming out of nowhere, a set dot in space, the yellow tank may reappear in the starting spot or may stay in the same place as "damaged" (can it really be considered damaged if it cannot be defeated?) as it were.
