Thanks for all the feedback.
The project was very ambitious and big for the game jam, but we wanted to realize the project the way we imagined it.
Unfortunately there was not enough time to complete the project in the end, so some elements of the game are missing.
The whole game works like this:
You play a person who can't remember anything due to illness. But by walking around in the old environment and discovering the world you can decide to remember important things in your life.
You start in an empty world where you cannot see anything.
With the left mouse button you shoot grey balls that allow you to see the world.
With the right mouse button, you shoot blue balls that serve to keep the objects in your memory forever.
The opponent is the big "nothing" represented by a black wall. All objects that are covered by the "nothing" are no longer able to be selected.
The goal is to find the old house where you lived with your family.
Best
Max
