2015-09-28: I dug out an old savegame from my archives. At the time, Jeppe told me that this was a nice little introduction to the 2D metroid games.
I've started playing this on mednafen. So much text in the beginning :/
I completed Sector 1/6 and entered Sector 2.
After Sector 2 comes Sector 4, of course. I've drained the electric water, so it's easier to traverse the area.
Working on Sector 3. I got the Super Missile, so I can get past the alien flesh walls.
The destruction caused by the powerful Samus Aran-X character are great examples of environmental storytelling. This game may look like it's from the early 90s, but the storytelling techniques betray it as a very modern game.
