Hello! I checked, and it seems you made the payment in July 2025. At that time, it was already impossible to make game payments here. I was only uploading DEMO here. I will send you an email regarding this.
Hmm... I thought quite a bit about how to answer. You might feel that way, but I wouldn't really recommend it. The greater the expectation, the greater the disappointment. You might go through a lot of trouble to get the game, but you will be disappointed because it is unfinished project. 😭 I am working as hard as I can on it. I think it would be best to purchase it when it is released on Steam.
