Well, they work on this game for free, while working on the game that ACTUALLY give them money to work on. So we should just be glad they found an artist who is kind enough to donate his art for this project OR that they have the spare money to invest in the project because Art is expensive especially good art, good music, etc. So I'm not complaining, I'm gladly gonna wait for months, even years as long as they keep updating the discord every now and then saying that they are working on it slowly or not.
Just remember it's very, very hard to make a visual novel, and work on one for free, and give quality work like they are doing? We should be forever grateful.
