Hi! We're glad you liked the game!
We don't plan to have after death lewd animations. We'd rather have them as a reward.
For the other questions, there are a lot of uncertainty as of now.
We'd love to update the game more and while we're not going to work on a sequel immediately after finish this, we'll come back to it.
Pirated versions are unavoidable and we must accept this fact. We hope that if players pirate our game and enjoy it they'll consider buying it to support us.
