Extremely good music and sound effects. And there's a different song every room! The art is a bit mixed in terms of details and styles and sometimes I feel like they are fighting each other a little bit. Gameplay wise, while there's no enemies, it was still quite fun hopping around gathering food items while listening to catchy tunes. Some of the jumps did end up too tough for me to make even after obtaining double jump, and I kind got stranded on the bottom of a level and couldn't get myself out. (But that seriously could just be me and my terrible platforming skill)
Overall I enjoyed the experience!
