Leaving Early Access: Aug 5, 2026

What the developers have to say:

Why Early Access?

“We use Early Access to gather real‑world player feedback, refine gameplay feel and level balance. We will expand levels, special blocks and audio content, and iterate the game together with community.”

Approximately how long will this game be in Early Access?

“Early Access is expected to last 6‑12 months. The timeline may adjust based on player feedback and development progress.”

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

“Full‑release plan includes extra chapters, more special mechanic blocks, complete achievements, leaderboards, further audio‑art polish, bug fixes and full‑content completion.”

What is the current state of the Early Access version?

“Core cube‑clearing, explosion combo and audio‑visual feedback are fully implemented. Early Access build contains complete base levels. Some special blocks and chapters are still under expansion and improvement.”

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

“Pricing will mostly stay stable during Early Access, and will rise slightly upon full release.”

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

“We will collect player feedback mainly through the Steam Community forums. Players are welcome to submit bug reports and suggestions about gameplay feel, level difficulty, visual effects and audio. We will check the community regularly, and take valuable feedback as an important reference for version iteration, level adjustment and feature optimization.
Not all suggestions can be adopted, but player experience will guide our development priorities. Development progress and changes will be shared via game update announcements.”
