Is the 5k ratings requirement really necessary? Why should players be required to give this game that many ratings so they can get a happy ending that should have already been in the game to begin with? I should note that there's nothing wrong with asking for a review, but when it's done like this, it's incredibly dishonest especially when games on this platform rely heavily on reviews to get seen by players. This tactic is like a giant slap to the face to your fellow game devs, some of whom wait months in-between for a single review.
I strongly suggest you reconsider your approach to this matter, and release the ending that your players and Zilas rightfully deserved from the very beginning.
