Did you take ispiration from some game in particular or it's totally your idea?

I definitely took inspiration from other sources. Such as DarkestDungeon for navigating tiles and getting surprised by enemies, I tried to do some procedural generation with terrain but it wasn't implemented that well. There was also this "duel" mechanic in the stand-alone GWENT card game that was the basis for combat.
And just general hexagonal board games and DnD maps, utilizing cards as resources.
