On Chapter 2 I'm unable to progress due to the game thinking I have not swallowed my prey not giving me the Fullness options of Rubbing my belly or Crushing my Prey (or whatever it was called) even though that Water Icon is an indication other wise.
Putting more thought to it, the game did say the slime escaped my belly relieved, which is where the Crushing my Prey skill happened. Swallow the other slime then went to Fullness aaaand the options are gone. Oh well will try again later just in case it's a me problem.
