The writing was pretty good, the use of the saving/loading mechanic was very creative (it reminded me of Undertale/DDLC, especially at the end). I really liked the moment that Brawn set his own Anchor Point in the middle of the battle, and you can tell because the boss has that same Meta Stasis animation on it.
I also like how the game teaches you how to use the mechanic, and then with the final boss shows exactly what this mechanic is capable of.
I am curious: is there anything left after "Little Tina" starts saying "..." whenever you return to an Anchor or when you start a new game?
