nice

I thought that by not dropping the knife i would get a different ending.

willhelm scream really? it has never been funny in any movie/show/game ever. it always just breaks immersion. and makes the author seem amateurish.

needs more endings.

Okay, I LOVED the beginning concept, especially when it almost started to feel like you were seeing yourself in the forest (kinda like a future echo idea - what your future self does you see, so you alter your behaviour and it ripples down the line). There isn't enough game element at the moment, choices need adding in etc, "spacbar" needs changing to "spacebar" and some slight graphic improvements to improve the atmosphere might help a lot.

BUT (and it's a J-Lo size butt), that you did this in 14 hours to see if you could, got something functional at the end of it which has atmosphere, a structure, charm and potential to become something pretty good is amazing! I hope you keep working on this as I'd love to see it as a fully made up game :)
