I agree with urodela, the enemy hitboxes should favor the player more. Also K was the harvest button for me, but the intro says it's H.
I really liked this idea! It was weird and fun, the destruction of the rooms as you ate was clever and made for a fun sort of "escape the destruction" feeling. My other big complaint that made it hard for me to finish was that the player has no control over the height of their jump. In some platformers it doesn't really matter, but in this one if a fire block is above and below a doorway there's no way to get through it without dying.
I did like this one quite a bit though, fun and creative submission
