I enjoy a game that not only breaks the fourth wall, but also one that questions your moral views. And it's not a consistent reminder or repetitive either, it leaves you in environments that was the result of your actions, letting you ponder 'Am I doing the right thing?'
And above all, you, the player, are the main character.
The battle system does get a little irritating after a while, but luckily the creator, Mortis Ghost, installed an Auto Battle system where your puppet, The Batter, can carry on a fight without you.
Might I add, this game and it's characters inspired UNDERTALE.
Let that seep in!
