Played 3.13. Warrior.
Make a black border on your sword icon exe it seems invisible for some settings.
Great juice overall, very nice music.
I love the moddability for card images, this should be a focal point for your marketing "you can REALLY design your card here!" (make some bullshit card with goku, john wick etc, go nuts). I dunno if this mod also goes to card border and table, but it should.
I'm not a card game guy (and never player slay of the spire), so take everything with salt:
My brother made me play magic arena once, so I understand something of this, and everything is clear, but tutorial asap. Stupid example: an angel has relentless, but in the explanation on the left side of the screen you say "does not get exhausted when attacking". I know because my brother talks only about magic, but I don't really know. Maybe it would be helpful to know where your game differs from magic, and maybe this is a super niche game FOR magic players, but a newbie needs everything explained.
tldr, copy and implement a magic and heartstone tutorial. "how to play" is not enough for a noob.
card design type needs to be more obvious (see yu-gi-oh). Multiple times I mistook a creature for a spell card.
Make lvlup standout more (also told u in stream, su dunno if it's already noted). Right now it seems a common notification.
I like your events, they remind me of hands of fate.
I don't like the damage to player/enemy sound effect, but I assume it's placeholder
It's nice you can access your menù from the battlefield, but the icon it's too hidden.
I played vs elemantal wind mage "make a random effect". At first glance those random effects seemed out of nowhere, then I noticed dice of doom. Tip, you need a log of what happens during the game, think of digital tabletops like neverwinter/mmos (dunno if other games already do this, or I'm asking too much).
I don't have the skills to have an opinion on card crafting.
Got to final boss of raid but got wiped out.
Only bug: after I lost I choose 'go to menu'. In the menu cursor was invisible and couldn't click anything. I had to reastart.
Not my kind of game, but I think it's cool. GL next DD.
