This was really nice!
Despite encountering some of the problems other people mentioned, it was sill a lot of fun to explore around the map and see al the nice art, listen to the music and just jump around. The only thing I think would have made this a better experience would be an indicator of how much heat the egg has been exposed too, but then again the jam is so short and this is not a very impactful thing so it doesnt make the experience less enjoyable.
This is a very good basis to expand upon without the limited time of a jam. I'd definitely consider even buying this as a commercial game if you guys decide to develop a full project out of this.
