Are the fifth hearts actually possible to unlock?
The fifth hearts are the "Devotion" hearts and will be unlockable via a special event in Act Three in a later update :)
do you have a rough timeframe for the next update?
I release updates every week :) The only exceptions being when I take one week off every two or three months to avoid burnout, or when a new system is taking longer than expected (which has only happened once in over three years).
