Yes, a Keen 1 version is easily possible.

Code: Select all

             $2E $A1 $805FW  $2E $A3 $7D95W  $90 $90 $90

When Keen presses up he will shoot up, when he presses down, he will shoot down. Otherwise he'll shoot left or right. The shot speeds involved are $0190W, $FE70W and $0000W (Left\up, right\down and still.) Keen uses the same shooting animation no matter what direction he shoots though.
