MY FEELS. I love Ninja Love so much. :'D The art is gorgeous, and the storyline makes me swoon. The energy renewal is very fair, and I really like how you're awarded with the tokens when you sign in. It's nice that a lot of items can be gotten free because of the Lucky Cat Slot. I mean, technically I get rice and rice balls more than I get anything else through the slots, but still, I'm not complaining.
If I had to talk about anything I dislike, I suppose it would be the increasingly ridiculously large number of passports you need to use as you progress through the game. I really can't waste money buying coins for passports, so I have to wait and save up tokens, which takes forever. It already took me a while to get six passports, and I imagine it'll be a complete nightmare when I have to get twelve. Darn crazy requirements. Nevertheless, all those pretty faces are worth it. ;D
