Here's a somewhat unique game for the FM77AV series. It reminds me a bit of the original Metal Gear for MSX and Famicom. It is an open world to explore, it has outdoor and indoor areas to explore, you navigate one static screen at a time, you pick up items to access new areas and further your exploration, and there are traps you have to avoid as you navigate the underground world.

They sometimes employ quite large sprites, especially during the boss fights.

there are a good variety of enemies and uniqueness in the environment from screen to screen.

No box for this one, but it did come with a manual.
