What the developers have to say:

Why Early Access?

“The community always comes up with great ideas, so I'm doing Early Access to give the game extra time to grow based on feedback!

I want every different playstyle to have fun and broken synergies that people can enjoy, with a focus on updates that buff skills to all be interesting in their own ways, instead of nerfing things.”

Approximately how long will this game be in Early Access?

“Roughly for about 3-6 months.”

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

“We plan to add new gameplay mechanics, new types of enemies and bosses, endgame progression systems, and new maps with different game modes. We intend to support and update even after it leaves early access.”

What is the current state of the Early Access version?

“Refer to the game's "About This" section for details.”

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

“The price will increase during major content milestones such as new game modes being added, and 1.0 release, but the game will still be priced affordably.”

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

“My Discord server & the Steam Forums are great ways to give any feedback and suggestions. I check them out all the time, so you can make sure that your idea doesn't get missed.”
