A delightful little game. I did not see any real reincarnation features or anything overly idle beyond (sit and wait for the pet to make little crystal things).

So on the face I would say its not exactly an idle/incremental but more of a fully active typing game (hacking + typing games are fun to me so I am a bit biased in my overall rating)

As a demo I would say its a solid one if a bit dry feeling (not sure how else to describe it, its functionally fun/enjoyable but feels lacking).
