!Eldritch Update Live!

Assassin at Crimson Keep is a short visual novel set in a dark, quasi-fantasy world.

After a botched assassination attempt, you pursue the King into his lair known as the Crimson Keep. Your small choices can have great consequences, either for good or for evil. 

Key Features:

  • Seven Different Endings (not including Game Overs)
  • 15-30 minutes per run-through
  • Small Choices Have Big Consequences 
  • Hand Drawn Art 
  • Original Music by Adrian James

!!!Free Steam Key with Purchase!!!


  • The Eldritch Update introduces includes the whole game, even though file size is smaller
  • There is no patch file to bring 1.0 up to date. As a result 1.0 saves are more than likely not compatible with Eldritch 1.1
  • 1.0 will remain up for posterity. While Eldritch 1.1 is the final and better version, maybe some people like the original better.

Hej! Just bought AaCK and looking forward to playing it!

One quick bit of feedback about the itch page: Various places say things like "Help this AaCK reach it's goal" and "You own this AaCK" which makes no sense and confused me for a while - I guess AaCK was entered in the field to describe the type of thing this is. "game" or "visual novel" makes more sense. Anyway, I am going to actually start playing now!

Ah, interesting. Thanks for the heads up! I’ll change it now.


You're welcome! Thanks for playing!

Really liked the game, and the art style is just beautiful. Do you have any plans on localizing it for other languages?

Thank you very much! That's always an encouragement to hear.

For localizing, nNo plans yet, unfortunately, though I am open to it. Just a matter of finding the right people (and time to implement it <-- that's the kicker).

If you ever get to implementing localization, I would gladly assist with translating the game into Russian for free (in case this language is on your list, of course). I already have some experience with game localization, and would be happy to help such a good game reach broader audience.

That was fun. Took me 30 minutes in total


I'm glad you liked it! My next one will be much longer (shameless plug, the prototype is already longer: https://shadowglass.itch.io/guildmaster).


You state the following on the game page above:

!!!Free Steam Key!!!

Yet there is no information on how to acquire/redeem such key.  Please provide this information to your audience.


Probably have to pay more than (0) to get a Steam Key.


Hmm, I remember there being an option to allow Steam keys even though it's free. Try going here and see if this will repopulate: https://itch.io/docs/buying/already-bought

Meanwhile, I'll look into what happened.

I'm inclined to believe there's no Steam key option available for those who obtained the game during the free promotion, likely by design.  I would appreciate an update to the main game page to let people know that the Steam key is only available to those who paid for the game.  Thanks so much for the temporary free giveaway and I look forward to my playthrough :)


Thanks for the info and for checking out my game. I've got a inquiry going on to see if I'm crazy or not. :P
