I wake up. I see email from Steam. I buy game. I go in without anything. The last ten minutes are me reading the PDF manual. I will play this again, I am positive. Game page on Steam here: https://store.steampowered.com/app/2395150/Demon_Lord_Reincarnation/

"Assemble a party, explore the dungeon, fight your way through hordes of monsters, and defeat the Demon Lord in this brutal dungeon crawler. Are you up to the challenge?"
