Short version: You'll be very pleased with this gem.
Long version: ↓
Die-Hard Roguelike / Deckbuilder fan here, beaten Knock on the Coffin Lid several times by now:
Got pretty much every well known and some niche Roguelike / Deckbuilder games on Steam
Over 1000 hours on Slay the Spire across various platforms, played it since its early stages

• You'll get the most beautiful and visual appealing Roguelike/Deckbuilder on the market.
  
• Plenty of VERY well written and designed encounters.
  
• 3 characters, with 4 different "specializations" (different starting deck, absolutely different character traits, resulting in a completely(!) different playstyle. So essentially, you have 12 characters to choose from.
  
• Equip-able gear with various traits (which has its' own attack animation and is visually shown on the character)
  
• Makes it feels more like a RPG
  
• Lets you change your gear midway through a run for a completely different playstyle, should you get some special cards or trinkets which would have a superb Synergy with gear-set xyz, or work well with the unique item y

But of course, the game isn't the holy grail, there are some flaws in its current EA build:

• No Keyboard controls (Devs responded already, Keyboard controls are confirmed and will be available in the future)
  
• Fast mode present, but not as fast as in StS (Speedhack compensates that, but denies proper Speedruns)
  
• Don't come with the expectation of a bazillion items and gear, this game is still EA

Last but not least: after beating the game once after 2 hours, I was zooming through the game with Speedhack on 6, insta-clicking cards, so feel free to multiple my remaining 8 hours with 6.

This is actually the first game since StS that gave me the same itch and entertainment level as our pinnacle of Roguelike Deckbuilders used to.
Knock on the Coffin Lid will certainly be no later than at its release on par with StS.
