Despite playing this so long ago, I still found myself thinking back to it every so often, off and on for 10 years now.
Imagine my pleasant surprise when I finally searched it up and found that it indeed still existed. That there was indeed a game to place this dim recollection, and a vaguely haunting feeling to. A moroseness of sorts, of thoughtful dwelling on the things that may have existed, but that one might never know. Before the Dictionary of Obscure Sorrows may or may not have put a name to this feeling, there was this game that encapsulated it.

very cool concept.

the screen gets blurry when i try to fast and high jump

Lovely abstract theory.

This game makes no sense! but good game design
