Now this blending of ideas looks damn cool. Moonsigil Atlas looks like it really warps deckbuilders into something quite unique, and I can't wait to check this one out. The developer said it's basically Tetris meets Slay the Spire, and as far as comparisons go it's quite a fun hook to think on.
Here you play your cards by positioning special magic sigils on the big crescent moon, playing as many as you can that you have the space to fit in. The game will have multiple characters to play as, along with hundreds of cards for a whole lot of possible decks to build.
Depending on where you place your sigils you might get bonuses for adjacency, overlap, and more. With some persisting between turns, or with ongoing effects, and enemies to face that can cast their own hostile sigils to mess with you too.
I really do love the style of this one. Check out their announcement trailer below:

There's a Steam demo page live for you to follow now too and the game will have Native Linux support. High up on my wishlist this goes!
Need a controller support though.
Hi, I'm one of the developers. The response to the playtest has been very encouraging (and a little overwhelming!). The comments we've received have really improved the game. Thanks for participating!
Controller support is on our critical feature list. As soon as the feature is ready, we'll be adding full controller/gamepad support to both the upcoming demo and the closed playtest :)
Thank you for caring enough about prospective customers to release a demo. Much appreciated.
Moonsigil Atlas had not crossed my radar before I read this article. It looks like something that I would enjoy, so I filled out the application form to become a playtester.
