Approximately how long will this game be in Early Access?

“About 3–6 months.”

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

“We plan to expand the game with additional stages, scenes, and cards, along with gameplay enhancements. We also aim to further optimize UI, art, and performance based on player feedback.”

What is the current state of the Early Access version?

“The Early Access version of Exo-Card Collector already includes all of the core gameplay features. Players can collect cards, manage their card book, trade cards on the dynamic shelf system, explore adventure stages to obtain card and pack rewards through idle or active play, and showcase their favorite cards in customizable display boxes. The current version already features 220 different cards to collect. The game also supports achievements, multiple language options, and a complete saving system.”

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