The developer, Whirlpool, has created a survey to get the opinions of users regarding NEKO-NIN exHeart. This is an excellent opportunity to let them know how you feel about the game and on future projects as well.
The survey only takes about 10 minutes so definitely let them know what's on your mind!
Thank you for your support!
