I enjoyed this, but wonder if it needs another mechanic to make the puzzles more challenging? All the levels can be solved quite easily at the moment by using your stamina to reach the next area with grapes in it until you've accessed and eaten all of them, then you just mop up the remaining boxes.
That routine can be disrupted a little by leaning into the movement constraint of needing to be one space away from a crate to chomp it, which could make one box in a group more important to remove than the others. But the introduction of another stamina-costing move (falling off a cliff?, pushing a box?) or old-fashioned variable snake length could let you design more complex puzzles.
