What the developers have to say:

Why Early Access?

“The community always comes up with great ideas, so I'm spending about 3 months in 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?

“The game will be in early access for about 3 months, and will continue to get support and updates after it leaves early access.”

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

“The full version will have more characters, new levels, new spells, new enemies, and other suggestions from the community.”

What is the current state of the Early Access version?

“You can play full runs from start to finish with all of the mechanics! There are various characters, spells, upgrade options, achievements, and more.”

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

“The price may increase a bit at launch depending on the amount of content that gets added.”

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.”
