Cool entry with a lot of personality!! I love a well made main menu and you nailed yours, super clean presentation and the spinning package is a great touch. The world is pretty neat and the little NPCs have a surprising amount of character. The dialogue for each character was amusing and always felt worthwhile to speak to each person. The platforming felt nice to control and I enjoyed the feeling of exploring the world. I wish there had been some sort of tutorial section as I had no idea how to deliver packages and couldn't figure out how to make any progress. I enjoyed my time hopping around the map and talking to new NPCs but unfortunately couldn't figure out the main gameplay loop at all got stuck on the second package. I was able to successfully throw it to the magic man on the castle roof but then it would restart me on that delivery again, even though there was no mustachio'd man near me. I think there's a fun game in here but the lack of direction made it difficult for me to find it, but and I really did enjoy the world feel and dialogue text. Keep up the good work!
edit: somehow I completely missed the intro NPC my first time...changed some things in my review.
