While I fully understand the sentiment, further development was never promised. It was released as is from the start. They were very upfront about it.
As members of the team went their own ways after graduation, further development is difficult as code and game assets are owned by individual members of the team so no individual member can continue to develop the game without permission from all the other members who are now scattered all over Sweden.
It would probably be easier to restart the project from scratch.
After graduation some of the former Anchored devs have gone to create games like Raft and Frog Climbers.
