The Doctor and Amy both have individual abilities, and when I say "abilities", I mean the most basic ass shit like the Doctor being able to push things while Amy can't, and Amy being able to walk over weak floor while the Doctor can't. This game came out in 2010 back when people wouldn't have batted an eye, but if it were released nowadays, Tumblr would have a field day. Upon death, the Doctor regenerates, but alas there's no playing as Peter Capalkino. When Amy dies, she... um, regenerates too... Okay.
