Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“I'm offering Early Access because Skyward Bastion is a game that benefits from community feedback during development. The core gameplay is in place, but other aspects of the game like balance, progression, difficulty scaling and replayability improve a lot when tested by real people.

As solo developer, Early Access is also a way to build the game together with you all, making sure the final version is the best possible experience for the audience.”

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 turrets, more enemies (and bosses!), upgrades, rounds, gameplay mechanics... and more surprises(?)

Oh and a visual upgrade!”

What is the current state of the Early Access version?

“The core gameplay is set and the first pack of turrets, enemies, bosses and mechanics are done.”

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, and send memes (?).

I'm also active on social media, forums, and Steam community channels to share ideas with you all!”
