Hi guys! It was quick, thanks to everyone who comments, I read all of you.) The patron is a temporary measure, I hope it is clear that I also need some kind of reward after all! I plan to complete this project in 2-3 months.
As for the size, this is Unity, what did you expect? This is not some renderings on RenPy, everything is completely in 3D. But the good news is, the whole storyline takes place in the house, so the size of the final game will not exceed 3-3.5 Gb. Also, I'm still learning it's only been 8 months since I started learning Unity, so in the future I will find more effective optimization methods, I hope))
