Good
- shooting down in mid air helps a lot. Crouch shooting is nice.
- enemies are less frustrating to deal with. Much easier than nes game.
- enemy movement isn't overly sporadic, spawning randomly and following Samus through rooms
Bad
- the mission in the game is not very exciting. Very straightforward
- some enemies are too thin. Really hard to hit with some beams (plasma)
- no map. The place is a huge maze and if u miss a Metroid or upgrade it can be an annoying trek back. At least maps in Metroid were color coded, which helped with backtracking. It's extra hard in this one cause no color.
