Hi Inateno, sorry that I took so much time before trying the demo on Newgrounds.
After looking to the comments below it seems you did some improvement between the moment you launch the demo and now. I enjoy the visual novel experience even if characters still have a lack of charisma (I think you should exagerate the physical traits and clothes of Elias Walker and Eliana should get more facial expressions).
On the game part, I think you should maybe make the board more purified, a cleaner board would probably make the game more accessible for newcommers.
I also get a bug where a duel showed the wrong numbers ( it was like my card was at 0 when the other one was at 4 but i was the one winning) It happenned only one time on the tests I've made on this version.
But it becomes more and more awesome everyday ;) keep the good work.
And for anyone who discover this, Inateno is also someone very open to discuss with to improve the game so don't hesitate and give feedbacks to help improve the game !
