I really enjoyed the game's atmosphere, and the visual aesthetics as a whole. The models, colours, light and fog were all very pleasant on the eye. I also find the playful, and a bit absurd, setting very fun.
In terms of what could be improved, I feel like the movement is rough. I often got my momentum killed by small pieces of geometry. The transfer of movement in jumping also feels strange, like my pumpkin's physics just freeze for the jump's build up, and then they come back again.
