This obscure Japan-only Success title is a collection of button-mashing minigames parodying the life of a Japanese salary man (your average white-collar wage worker). If you're looking for weird Japanese humor, look no further than this run.
This is an improvement over the last run (http://tasvideos.org/1522M.html) , using two players instead of one.
