What the developers have to say:

Why Early Access?

“We'd like Overdungeon to be easy to access, and involve and know community feedback as the game progress.
Additionally we have to adjust card and relic balances by community feedback and we'd like to know incredible methods that we weren't aware of.”

Approximately how long will this game be in Early Access?

“We aren't sure how long it will take but at least more than 1 year since we will add new characters and dungeons. We have to adjust game balance with whole parameters and we'd like to provide highest quality of new-style card game for community.”

Patch No.99 Daily Update v1.1.73 (Consecutive 91 days! Guinness Challenge!)

Thank you for coming to read today too!

Yesterday I wrote that Star of Extinction will fall "20 times" after upgrading.
The correct number of stars is "18" as it is in the game!

B bug fix
★ Fixed a bug that old relic did not appear in Deadly.
★ Fixed a bug that Mortar built by relic shot once at the beginning of the combat.
★ Fixed the Barrier bug. The bug that Mortar didn't work correctly was related to this. Now it's fixed.
★ Fixed a bug that started with the daily dungeon relics when you canceled Daily Challenge and headed to another dungeon.

Thank you for reporting!

Balance adjustment
★ Change the rarity of the Execution Button to common.

★ The following adjustments were made for ""Easy Mode"".
- We deleted the rule that relic can be obtained in normal battles. It was way too easier than we expected.
· Changed one of the relics at the beginning of the adventure. Let you enjoy drawing additional cards!

★ The effect of "Unstable" has been changed as follows.
"Exhausted at the end of your turn. If you play this card once, Unstable will be removed."

★ Deleted Unstable from Loaded Dice. It exceeded the limit that player could conscious. "Unstable" should only be given by the effect of special cards and other relics.

UI / UX change
★ The effect of changing the number of traps set is now correctly shown in the text of the trap card.
★ The description of "Anywhere" is displayed only in ""Animal"" and "Building". We decided to exclude "Attack" and "Spell" because there is no placement restriction.

■ Introduction of current development ■
★ New effect for some cards!
★ New character!
★ Season Dungeon Levels!
