What the developers have to say:

Why Early Access?

“As a solo developer I would love the community's help with balancing, coming up with ideas for improvements, and bug reports. Since this is also my first game released on Steam, I would like to be cautious with the release. I look forward to your feedback!”

Approximately how long will this game be in Early Access?

“The game will be Early Access for only a short time as it is currently mostly feature-complete. I am aiming for a release in early March, 2019.”

How is the full version planned to differ from the Early Access version?

“The full version will add a final, third act to the story. If there is enough interest in other features, such as New Game+, I would love to add those as well.”

What is the current state of the Early Access version?

“Near feature-complete, and includes everything listed in the "About" section on this page. However, the Early Access version will not include the final third act of the story. Improving balance, tweaking features, and finishing the final act will be the main focus. Although unlikely, progress may be lost between updates during Early Access.”

Will the game be priced differently during and after Early Access?

“The price will be the same.”

How are you planning on involving the Community in your development process?

“I will listen to all feedback from players, especially regarding balance and bugs, but any ideas for new or improved content is more than welcome. Please visit the Steam Discussion boards or email: mark (at) RatsBatsAndBones (dot) com.”
