Nice game and interesting take on the theme. The music in the intro was really nice and the atmosphere as well in total. Short game, but still left an impression. Cheers!
Gameplay wise, somehow the movement felt really janky at times and actually rolling and rotating did not seem feasible to be used instead of just grabbing and pulling. Maybe some mechanic to push with the Tether would've been nice and give more control to the player to manipulate the world as well?
