Zaku, Unboxing+Play, Atari Lynx, Shmup, collectors item, rare

Out of Print, release by Super Fighter team, very rare item.
I think 1000 copies in total were made, the last run was sold out in 2016 or so.
The "holy grail" of Lynx homebrews.
Technical showpiece for the system, with parallax backgrounds, huge sprites and 60FPS.
The gameplay is really good, I did not like the drawn out boss battles and short stages though.
