@KeyOfTwilight Wow! This is a demo? I suppose it must be unfinished because it's huge! You have the mortal world encounters, summoning, mining, crafting, farming, lore, an in-game economy system players must learn to git gud, a time system, original art, and more! The font isn't working quite right in all areas of the game and the writing has some typos/minor translation issues...but your English es muy bueno! You start off with some good hints about how the world works. I had difficulty figuring anything else out, so I blew my crystals on 4 summon cards, stowed 2 in the chest, then summoned a slime and went to the mortal world where we mined ore and took down jellyfish until......Slurry died. Game over. Ah, well. I guess my biggest suggestion would be a tutorial system since your game is rather expansive. Walk the new player through one summons, one crafting, one farming, and one encounter with mining so they get the idea of how everything works. I do like a challenge, so I'll be playing again and again. Color me impressed!
