What the developers have to say:

Why Early Access?

“We are doing early access because we want players to help us decide what levels to add, provide input on the game, and help us select what collectables we should add. We will have steam discussions with everyone who wants to engage with us during early access to help make the best collectathon platformer out there.”

Approximately how long will this game be in Early Access?

“The game will be in early access once it is feature complete. We want to have it in early access for at least 3 to 6 months. It may be in early access longer if we get a huge amount of community feedback as we want to consider everyones ideas.”

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

“We want to achieve our goal of making a fun voxel platformer and collectathon with lots of bite sized levels that everyone can enjoy. There is a classic gamer difficulty mode to the game and a easier mode without game overs. We want to have everyone in the early access process help us make the best possible platformer, with their feedback. It would be awesome to have people help us decide new moves for Big Jay and ideas for cool levels.”

What is the current state of the Early Access version?

“The game has 5 levels currently, we want to aim for at least 10. What we do for the theme of the remaining levels will be decided by the community. Big Jay's is currently a fun platformer with bite sized levels and a some fun platforming mechanics with the fat rat himself Big Jay.”

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

“No the game will be the same price in early access as release.”

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

“I want as much input from the community as they provide. There will be open steam discussion threads and we will take any feedback seriously.”
