the app has nice features but I wish it was available in landscape mode. I want to cast it to a screen and it just looks hideous. it would also be nice if there would be a mode that just shows everything needed when your in battle and puts the music under it. just like it would be in game. done with battle click a button and music switches over. and during battle it shows a some of the battle rules. like a true companion next to your game.

I was very pleasantly surprised by the app. For those that already have the board game it's a very nice tool, makes playing a bit easier but also adds lots of immersion. And even if you don't have the game yet or at all, it does make it technically possible to play it with Proxies which was interesting.

When it comes to cool features, this app has lots of things to check out, like the soundtracks, the progress tracking or the rulebook to name a few. What I do wish we had was a more solid way of saving our progress however. I do appreciate that you made this app and that it's free, but I really feel like the app would be way better if the deck saving feature would show a little album to pick cards from, like in TCGs. I currently just take pictures of the decks to save. Thanks for your work!!
