Good hook at the beginning; gets me interested in your world. Combat starts and I can’t do very much of anything at all. There’s a weird white line thing in the middle of my screen. Zoom out and see, “oh, it’s surrounding the half of the screen that I’m hovering over – that wasn’t very obvious”. Click the left half of the screen to put my fighter there. Game says, “now click the start combat button to begin.” It doesn’t work. Neither does the “Next” button that appeared at the bottom center of the screen. Stuck forever. Quit game. Write this post.
I really wish I got to see more. Your art style is cool. The world seems fascinating.
