Sky Destroyer lets the player control a Japanese plane during World War II as it destroys submarines and planes, but not the sky itself.
Secret Message#
Start a new game, then take damage to both the left and right wings before crash landing. Do this three times and on the "GAME OVER" screen, a secret message saying "PRESENTS BY KOBAYASI & OHTSUKA" will appear.
The identity of "Ohtsuka" is unclear, but "Kobayasi" may be Masahiro Kobayashi, who was credited as a programmer in games by Home Data.
