That was neat! Definitely on the fair side as far as rage platformers go; those boxes caused the most trouble! I enjoyed working around the limitations and gimmicks. Although, I'm not sure if the blurry world changes much about the platforming.
The main character is a stand-out in the design—they have a goofy sort of aloofness about them, and the design does a good job indicating their blocky hitbox.
The music is a little repetitive and flat, but that sour chord in the middle does well reflecting the unlucky nature of the game itself!
Objects don't seem to align with the pixel grid.
All-in-all, good work! Congratulations on the submission!
