one of the ends is reach day 60(or 70) with mediocre room (like the room which uses things you can just buy from towns)
another one is making all the decor/food on the highest level and maintaining that until the game ends
another thing is if you collect all the characters which raises FOOD level you'll get Iron Chef, another if you collect the characters with INTEL, you'll get Lua Inn or something ending, if you conquer the lord, you'll get the legendary adventurer ending, for maid ending you need to conquer the priestess, the mage, and the thief.... you can then try for other endings by conquering the Warrior, the Ranger, and the Minstrel... another one is the Samurai and the Ninja along with the Amazon woman, then just the demon lord....
