What the developers have to say:

Why Early Access?

“I am offering Early Access because Skyward Bastion is a game that benefits from community feedback during development. The core gameplay is already implemented, but aspects such as balance, progression, difficulty, and replayability improve greatly when tested by real players.

As an independent developer, Early Access is a great way to build the game together with you, making sure the final version delivers the best experience possible.”

Approximately how long will this game be in Early Access?

“I estimate around a year.”

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

“More towers, enemies —and bosses!—, upgrades, waves, mechanics, and more map-generated elements with their own unique mechanics... and maybe a surprise or two.”

What is the current state of the Early Access version?

“Early Access content:

- Procedurally generated map so every run feels different.
- 25 waves of challenging enemies spread across 2 factions.
- 2 final bosses, one for each enemy faction.
- 5 unique towers, each with multiple upgrades.
- More than 100 unlockable upgrades.

All of this content will continue to expand during Early Access with new towers, enemies, upgrades, bosses, and mechanics.”

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

“The price may increase slightly each time new content is added, proportionally.”

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

“Skyward Bastion has a public Discord server where you can share feedback, report bugs, send memes, and talk about the game.

I am also active on social media, forums, and the Steam community channels to share ideas with you.”
