Thanks for the feedback!
It helps me understand my mistakes and improve as a developer.
That's a good point.
But I only put it as paid as an “advance payment” for the sequel that will come out as an update and people won't have to pay for it.
If I can't improve the game and the script then I'll leave it free.
And yes, in the game's story mode you do have to walk a lot. I didn't like it that much, but my friends told me “it was good” and advised me to publish the game.
However, I don't know if you've played the survival mode, which is more strategic and fast-paced, like FNAF, giving you a different experience.
