The majority of these were filled out over the years but I don't see myself making it to the end of the alphabet (sorry ZAPAZOIDS!).

23 months and 2800+ levels later, the above statement is no longer true.

If playing every level on knyttlevels.com is a marathon, I am currently about 10 steps away from the finish line. My legs feel like jelly, I've had a rock in my left shoe for the last 12km, but there's a smile on my face. About 60 levels have been released after their respective posts, so those ratings will come in the final wrap-up post when I can officially say that I've played every level on knyttlevels.com. Until then...

The usual disclaimer: I don't consider myself an authority on what makes a "good" level. It's a lot easier for me to fill in a single letter on a spreadsheet than spend hours making these levels so if a particular grade seems unfair I am more than happy to give more in-depth thoughts on any particular level.

As always, these ratings aren't meant to discourage anyone or be harsh. Making a level always beats not making a level.


What each grade corresponds to:   

OUTDATED   Obsolete versions of levels (see newer version for review)     
N/A  Tileset showcases, demos, etc. that can't be judged for gameplay     
---   ---     
F   Broken / flawed to the point of unplayable     
D   Severe issues (see criteria below) that makes completing the level unenjoyable / will not replay     
C   Average levels / no strong feelings one way or the other / good aspects counteracted by flaws     
B   Great levels that are replayable, or great level concepts       
A   Must-play levels     


Things that may negatively impact grade (-):               
Broken levels           
Random tile or enemy spam           
Excessive "hallway screens" that pad-out level with no challenge or noteworthy visuals           
Unnessesarily long walking period before recieving run powerup (unrelated to challenge)           
Arbitrary hidden spikes / invisible death tiles           
Wall clipping on screen transitions / void pits           
Poor distinction between foreground / background tiles           
Poor save point placement (e.g. save point > multple hallway screens > challenge)           
Surprise death by environment/enemy immediately on screen transition           


While playing each level, I've considered its gameplay (challenge, platforming, puzzle) , art (quality of assets/tileset), worldbuilding (unique lore, worlds that feel "alive"), atmosphere (mood), music, and storytelling. My ratings are gameplay-forward, meaning, for example, that a "fun to play" level with average graphics typically will be rated higher than a tedious level with great graphics.


I'm biased in favor of (+):
difficulty:   hard / very hard
genre:   puzzles
art style:   simple and stylized (e.g. Hostile Landscape) can score just as well as 'realistic / heavily detailed' art
mechanic:   use of minimap
   
I'm biased against (-):
genre: mazes   
genre: massive exploration levels   


Without further to do...

Granted. Your new life body can only breathe chlorine so you die again pretty quickly.

I wish it would stop raining already.

Fantastic. Adding the GC's to an already great level really elevates it.

I do love GC levels.

Granted! You have a new nerdy theatre friend named Robert. Unfortunately he only wants to see avant-garde collage plays scored with totalism music. Lucinda would go to the theatre with you because she has been meaning to see more plays but she lives 4000 miles away.

I wish it was cooler to listen to Enya.

well well I have to do it again then 
thank you Lucinda ;-)
