So New Craft3DS is basically a block-like game sort of like Minecraft but 2D. There's not much content on it right now but I personally love playing the game and usually when I make games I play for testing and wish it was over, instead of playing for fun. But this game is being addicting and when it does get sort of get old I just add something else. My main goal at least is to survive and I don't know if it's hard to survive but I always feel like it feels a little like Don't Starve where no matter what you do next you have to do something else. But I know everything about the game so I can't speak for others.
Anyway just wanted to share. I honestly spend maybe 2 hours minimum a day playing this game. Even though I feel like there's nothing to do in it, I just mine stuff or do something anyway.
