Neat concept, though right now, the main interaction mainly felt like a chore and not like it added to the gameplay. I guess if there were enemies or some other danger if you stayed in the same spot for too long, this would drastically change how it feels, and I appreciate that three hours are a very short time, especially if you’re working with a new engine for the first time. I think the idea does have potential, nicely done.
(also props to you for jumping off the Unity ship ;))
