What the developers have to say:

Why Early Access?

“In its current stage, GB BASIC is fully usable. However, I am still testing the tool and will make updates based on the feedback I get from the users. It really motivates me that people enjoy the tool. I therefore greatly appreciate feedback and suggestions, so that I can continue developing the tool to make it more efficient and friendly for everyone to use.”

Approximately how long will this game be in Early Access?

“GB BASIC will be out of early access when the main features have been validated and the application is confirmed to be mostly bug free. This might take roughly 6 - 12 months, but it ultimately depends on the feedback I get along the way.”

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

“During development, I plan to continually update the scenes, actors, controllers, UI, UX, runtime, syntax, compiler and pipeline, gradually move the application towards its final state.”

What is the current state of the Early Access version?

“All the features listed in the "About This" section below are already implemented, including writting code, making assets, compiling projects, running with the built-in emulator, exporting to runnable ROM, etc. The early access version is perfectly usable and not very buggy. You can already use it now.”

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

“I don't plan to change the price.”

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

“I'll listen to user voice from the Steam forums here. I'm ready to source feedback, suggestions, and hunt down whatever bugs you uncover.”
