What the developers have to say:

Why Early Access?

TL;DR: Slay the Spire currently has loads of content and lots of polish. We want to use Early Access to make it even better. We will be releasing updates every two weeks with new content, fixes, and incorporating feedback. To thank our supporters, Slay the Spire will be discounted during EA!


We believe that games that make best use of Early Access are the ones that actively engage with their communities. Frequent updates based on feedback and community input is exactly what we want to provide. By putting Slay the Spire into the hands of the players, we can make an already fun experience even better.”

Approximately how long will this game be in Early Access?

“The game will be in Early Access for around 4-8 months. We have been working on Slay the Spire for over 2 years, and believe that this is the amount of time needed to finish up the game with all of the content and polish that we want.”

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

“The full version will have lots of additional and improved content, including a new character with an entirely new card set. Leaderboards, daily runs, and social features will be incorporated as the community grows. We will be directly looking to the community to determine how and when new features and content gets added.”

What is the current state of the Early Access version?

“Currently there are:

  • Two core characters that each have their own unique set of cards.
  • ~200 cards, most with unique upgrades.
  • 50+ unique combat encounters.
  • 9 different bosses
  • 100+ different items to be found.

At the current stage, Slay the Spire already has tons of content to explore and great replayability. Right now, fully beating the game takes an average of about 15-30 hours. The main focus of Early Access will be harnessing community feedback to improve the game even further.”

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

“Yes. Early Access supporters will receive a lower price. We plan to raise the price when the full game is released.”

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

“Working with the community is the heart of why Slay the Spire is going Early Access. Throughout the Early Access process we will be working with the community to improve the game.

Community members will have the chance to have their own card ideas implemented into Slay the Spire! Details on this will be coming soon.

Nobody is better at discovering broken strategies than a thriving community. Through listening to your feedback, balance will be continually refined.

All ideas and feedback will be welcomed and seriously looked at. Maybe your sweet card idea will even make it into the game!

For the last 2 years we have been tirelessly fixing bugs with a team of internal testers. However, with so many permutations of cards and new content coming in, there is bound to be more issues. We believe that having a bug free experience is key in immersing yourself into the game.

With so many cards (and text) there is a lot to translate. We want Slay the Spire to be seen by as many people around the world as possible, and we cannot do it without community support. Players that understand the game on a deep and technical level always create better translations than outsourcing to non-players. Stay tuned for more.”

Weekly Patch 20: Immolate

Hey everyone,

It's patch day!

Card Library Tabs
We worked on a UI to improve the Card Library. Players no longer need to scroll as much when trying to view cards. This is especially useful as we add more card-related content in the future.

Card Quick Select
You can now select cards by pressing numbers 0 - 9. If you want to view the corresponding hotkeys, they can be turned on in the Game Settings. Here it is in action.

Card Reworks
We've been working on a lot of cards over at Mega Crit headquarters for our third character. While in the process, we also reworked some of our most unpopular cards.

There will probably many reworks in the future so we're trying out a new format. Pictures!

Reckless Charge
Reckless charge is now Common and shuffles a Dazed into your draw pile rather than making you Vulnerable.

Immolate now costs 2, deals considerably more damage, and shuffles a Burn into your draw pile.

Wraith Form
Wraith Form is completely reworked to give you 3 turns of Intangible while progressively decreasing your Dexterity each turn.

Patch Notes

  • Awakened One nerf. Curiousity is now 2 -> 1. Ascension: 3 -> 2.
  • Cleave card damage buff. 7 -> 8 (10 -> 11).
  • Combust+ card damage buff. 6 -> 7.
  • Seeds are now Timestamp based and "seed_source_timestamp" has been added to .run files.
  • Wild Strike card is now Uncommon.

Bug Fixes
  • Card Randomizer (affects rarity droprates of cards) is now correctly reset when starting a new run.
  • Card Randomizer values are properly saved/loaded now.
  • Edge case fixes for incorrect Block rounding with multiple powers.
  • Fix for chests giving the wrong relic rarity.
  • Fixed incorrect score calculation from Collector bonus.
  • Potential fix for End of Turn card effects.
  • Potential fix for Pandora's Box and Calling Bell issues and exploits.
  • Seed no longer flashes when you hit cancel in Seed Panel.
  • Statuses and Curses autoplay at end of turn again.
  • Typo fix in Pandora's Box helper text.
  • Unceasing Top relic + Queueing End Turn should now function properly together.
  • Unceasing Top relic no longer triggers after Statuses and Curses autoplay.
  • Wording fixes in Sensory Stone event.
