About this game

Keeper of Secrets, congratulations on entering Mythag University.

This world is dying.

Hundreds of years ago, Dissolution came with no signs. Life, consciousness, memories...All the existence that humans once gave meaning to were erased by Dissolution.

Yet people were kept in the dark.
Confronted with this hidden and indescribable disaster, Mythag University, as one of the few who is well aware of this fact, is determined to fight against this vast crisis by waking up the power that shares the same source of the disaster and connecting the humanoid weapons that are on the edge of insanity.

If everything is bound to be forgotten, are you willing to testify that the world has once existed? Will you carry the secret on your back and walk on by?
In the witness of the gravestone, may the Silver Key guide your way.

Welcome aboard, Keeper of Secrets.

In this misty British-style world, you shall carry the secret of the times for the sake of all life.
In the crisis of Dissolution, grace and power will be with you everywhere you go.
Arrange your team, and wake the ones who share the same source of disasters.
Go through Rougelite game levels, and uncover the unspeakable truth with your strategy.
Experience this grand story with multiple chapters. You will find the trueness in this broken world.

My new hyperfixation! I'm still at the prologue though. The art style is so freakin awesome! The story is so engaging (I love Doll and Olgier the most by the way). The voice of the characters are so good! I love Doll's the most. Though she sounds kinda condescending, but still super calming and kinda...rawr? Anyways, I haven't gotten through the prologue but I'm already liking it. Gonna give another review later. Though, would've been better if we could customize our character :3.

very cool game!! the design is beautiful and the gameplay actually makes me use my brain, but I do think more animations (like some character animations at the home screen + small animation sprites for the story) and some more UI tweaks would make it even more gorgeous. the game is very generous, already got 4-5 SSR and I'm only lvl 5 :) i do agree that the AI translated texts can be confusing at times and can drive ppl away from this game, hoping for proper localisation!

One of the best games I've ever played! The gameplay offers a ton of content, with a variety of mechanics, game modes, and challenges that keep things fresh. It's also very F2P friendly. The art style and soundtrack are immaculate, and the story is genuinely PEAK. Overall, it's a game I can see myself playing for years and not get bored, just because I REALLY REALLY LIKE it.
