Wow, love the tension in this game. Probably one of my favorite uses of a companion in a game too. I would love to see this turned into a full game with more puzzles designed around needing to be separate from the drone.
I'd like the player human character to have a couple more uses than walking on slopes and picking up the drone so I could use my human capabilities in tandem with the robot.
I can also see this as a horror game where I need to protect the robot and myself using distractions or AI that act different when around the player or drone. Maybe a little rat creature tries to steal the drone away but you can run up to it as the player and scare it off. Or maybe a larger creature comes at the player and you can use the drone light to scare it off.
That's just ideas if you plan on going forward. This is one of my favorite games from the jam, too bad you couldn't submit in time :(
Amazing work though!
