The gameplay was fun, the environment was neat, the music was nice, but the climax was very bad in my opinion...it was very anticlimactic... Really.. I had all the accomplishments and ran 1108m before giving up. [Spoilerish] The ending wasn't even pictured as being fearless it ended same as exactly every other run where you look terrified except this time there's a poof and happily ever after. I expected the girl to show some bravery and stand up against her nightmare(as suggested in the author comments), not her nightmare just disappearing randomly after getting all of the achievements. I even thought a game like this would have an even better ending if you avoiding killing any animals along the way, but that seemed impractical with how some of them are placed and gave up on it when there was a wolf standing right under the skulls in that giant fire way. I found it strange that in order to defeat death you have to kill animals to do so.
I feel the ending would have been better if the sun just slowly started coming up and clearing the fog as you ran to encourage players to try harder as theyre getting closer to winning.
The meaning in this game feels like "Give up and you win." as the run after the 500m is completely doable but doing them results in... nothing and i didn't seem to see any indication that i finished. OR another end i suggest is like a secret end where if you run 1000m with complete achievements you will run into a dead end, but the girl will turn around and start chasing the nightmare with her sword cause... you know.. she isn't scared now or something.
Overall its really good, but i just didn't like the end.
