i just got a duo, so i'm going through magic engine randomly trying some games...and...somer assault for tg16...

you're a slinky, except you can shoot...chess pieces and such...powerups (speed so far) are zodiac signs. you can jump from ceiling to floor, vice versa. very strange, but not too bad. it's an atlus game (did they used to make alot of games for turbo?).
