Hi. Thanks playing my game:)
Collecting spheres provides fuel for a greater range of movement as the player explores and interacts with the game world.
In this build the player is pretty much left to explore, observe and figure out how the world works on their own.
One aim of the demo is to get player feedback - how much hinting and guidance (if any) should be added to the final game design is a big part of that process so all thoughts, comments and suggestions welcome!
