Thank you for your kind words. We have worked a lot on the characters and their possible arcs throughout the game. With this story, we wanted to explore the psychological toll of having unexpected superpowers, or mutations if you will. The impracticality of some of the characters' abilities is something we hope to deal with in a realistic and grounded way.
Without spoiling too much, Subject 2 getting some assistance from someone (who depends on the group dynamics), is brought up later in the game. If he were to make it to safety, assistive devices for people with limb deficiency (and of course bidets), would give him independence. Still, his body is proving a lot to adapt to, though not as much in a practical sense as in terms of others' and his own perception of himself.
