Steam has denied the game, so it won't be coming there

Steam is infamous for censoring games that resemble anime and contain more sexual themes. A relatively recent example was the game "Order Us!" which got taken down because they deemed that one of the characters was a minor due to her having a smaller bust size, even though the characters are over 18. If you want to check it out the game for yourself here's a link to the demo with the devlog having the full game links.
