All I have to say is. Wow. So cool.
The character designs are so... unique and fitting of the theme. I really like them. Especially some of the enemy character designs whoa.. Just a lot of whoa.
Now as for the combat. I'm a bit ambivalent on this. On one hand, the card combat can be quite interesting using colored affinites akin to water/grass/fire using the colored triangle, circles and squares. And effects do change the outcome of the battle in some ways than others. But card games like this, with certain elements, you're at the mercy of the card pool you got at the start. If you don't get lucky or the enemy has cards you're weak against, you're at the mercy of getting curb stomped. Some of the ways the shuffling mechanics do can shift the odds in your favor but its very RNG dependent. The second battle is egregious in particular because of the poison card, which gradually poisons you and lose your damage. I think this issue is something that's a lot harder to resolve on account of card games being very RNG oriented to begin with. Trust me, I tried to create the card idea too for my game as the initial base concept and dropped it on account of the RNG factor to it all.
UI wise, the way you interact feels a little clunky. Its kinda hard to select the cards proper because the way you select the cards, the phase changes and the UX feels off? I know how hard it is to make something of this nature. Especially with all the randomized factors at play so I can't really put a negative critique on that or a more clearer description of how it felt off to me. Its more of a gut feeling on my end.
The story itself seems to be hinting at some demonic/eldritchian event happening. And our "hero" may not be the benevolent character we perceive, subverting our expectations.
Some spelling issues wise (unless they were intentional), this game certainly is intriguing and Act 4 might take us to interesting places too. Ultimately, I liked the character design and the story more than the gameplay with this one. Hopefully you'll get to continue through this adventure and complete the story you wish to tell with this.
This is probably one example. That's supposed to be a keyboard right? Listing it off can be a bit of a chore. Because there's more past the battle stage.
