This is a nicely polished game. The idea of a potato running around the sharp rocks is a funny concept. I would suggest selecting a different button for dash. I tried both WASD and Arrows for basic movement and neither felt like a natural combination with X. My best performance was with WASD-Space with left hand, and then just use my right hand index finger on X to dash.
As a platformer, this required a lot of precision movement. For me the game was very difficult to make progress. The visuals and audio went really well together. I liked the object permanence for the potato shreds on the ground. For the dash and death sounds...did you record some swishing sounds with your mouth?! They were great.
Great submission.
