PLATFORM ADVENTURE
Knytt Stories (PC, 2007)
Subgenre: 2D Metroid-like without combat (can't attack enemies)
Movement Mechanics: Toggled glide jump (umbrella item), double jump, wall jump/climb
Other: Includes a level/game designer tool, Flip screen (non-scrolling)
Somewhat non-linear structure (can grab some ability items in any order (double jump and high jump, more?), alternate path above the spike creature that you're supposed to use the hologram to get past in the west - lets you bypass the final area)
Frequent save points (one slot per game only - leads to backtracking)
Some interesting abilities (hologram/clone - not attacked by enemies so can be used to bypass them and grab certain items)
One hit deaths
Difficulty options (easy-hard but can only pick easy or normal at first)
Some shortcuts
Various neutral creatures (can't interact with them however)
Your avatar glows when near false walls
Some environmental changes when backtracking (black eastern area after getting the eyeball to see invisible enemies and blocks, after beating the game)
One alternate ending (go to the top right of the post-game congratulations room then find the two keys that are left then go through the red key gate in the blue spiky area)
Decent and optional tutorial though it doesn't explain all mechanics and items
Silent protagonist and some NPCs don't say anything
No pause menu means you have to use a key combination or the window menu for restarting from the last save point
Control config - can't remap the controls after you start playing however
Some notable cons:
No map
No fast travel
Some one-way paths early on
Too many empty rooms and not enough hidden paths or items
Some backtracking
Very short (below 1h if you know where to go)
Playthrough (Speedrun) - Video Review - Mini Review
Influenced by: Within a Deep Forest, probably Metroid series
Infuenced: Saira, NightSky?
