Thanks for the comment! Yes, the size of the player game object changes based on if they die (they get bigger) or if they shoot their companion robot (they get smaller).
We aim to create some simple puzzles around that mechanic, but our main aim was to create a satire out of the absurdity that the little robot is helping you escape and you have to destroy him over and over again to get through the game. Getting bigger on death was just an extra idea to counteract getting smaller.
All of this will hopefully make more sense, once we will implement narration from the robot.
