Amazing work! Especially with the loops and everything, I especially like how the atmopshere felt flat and one-dimensional...

.... especially when it should be since it was the MC's personal hell. I also like how Lucille wasn't all that malevolent for a Devil, she's just playing along hoping you'll wake up to your senses. I do wish that each visit corresponds to the circle of Hell, like in the 2nd visit the MC is heartbroken because they were cheated by their lover and in the 3rd visit they were like a hungry beggar who was able to scrounge up enough money to buy some food in the cafe. As each visits progress the MC slowly gains awareness so the ending didn't seem sudden.
But those are just my personal thoughts, I loved the ending and especially when we can choose different names. Great game! Love it~!
