Hi!
Releasing a quest standalone version is a really high priority for us! But before we are able to develop this, we have to work on refining a few of our systems first (such as our semen).
Importing character from other games is sadly not possible. If you are not able to find the character that you like, or you are not able to make it yourself, then you can consider becoming a patreon where you can request specific characters to be made for the game!
