The music was nice, giving Tetrisphere vibes.
On presentation: It’s a simple game and your actions have reasonable feedback. I actually think they may have gone a bit too far: the slowdown when you jump is a bit overextended to the point of being jarring. Moreover, your description promises a minimalist pixel art style, yet no two elements have the same pixel size. The parallax backgrounds are a nice touch, but they don’t quite cycle cleanly; occasionally there are visible jumps. All of these are little things, but taken together they detract from having a good, cohesive experience. I like that the traffic cone enemy gives an anticipation as to what it’s going to do, and you give plenty of time to react to everything.
On gameplay: I reached a score of 300 before letting go of the controls and letting the run end. I mentioned earlier how there’s plenty of anticipation and room to react. On the flip side, this means there is no challenge in the game, and after a couple hundred points rack up it’s hard to stay engaged. It’s hard to overcome that in an endless runner, but one approach might be to slowly dole out new kinds of hazards, or to have any kind of non-flat difficulty curve.
On the limitation: You certainly used it, the gameplay elements are constantly in motion.
