PLATFORM ADVENTURE
Metroid II: Return of Samus (GB, 1991)
Subgenre: Killathon/Search & destroy mission
Movement Mechanics: Roll on walls and ceilings w/ Spider Ball, Semi-flight via the Space Jump ability
Mostly linear structure (can change the order you do the bosses in at areas 4/5 with enough e-tanks and space jump, can do area 8 after area 9 but you'd have to backtrack quite far)
No in-game map (basic map of the first area in the manual)
Save feature (fairly frequent save points (one slot, can't choose between slots in the main menu and can't view your current progress (only indicator is the Metroid counter shown in-game)
Three different endings depending on completion time
One neutral creature (Flitts - some are basically disappearing platforms and others moving platforms)
