Hello Zakaries,
Due to a number of reasons including personal events in the lives our small team, our current ongoing projects, and the difficulties we've had implementing steam achievements for games developed in Nanonovel, it is still a goal we'd like to accomplish at some point, but we have no projection for when we might be able to.
We're very sorry for the inconvenience... we understand steam achievements are important to a lot of our fans, and are still hopeful to achieve (ha) this in the future.
We also apologize for not responding via steam... there is currently no implementation for developers to receive notifications about comments, so it is rare for us to see them.
In the meantime, we hope you continue to enjoy our projects.
