Yandev will be 68 years old when the game finishes

I used to be really into yandere simulator as a teen and got back into it before uni starts up again and only 2 rivals are out! It made me wonder how long this game will actually take to be made and I did some calculations.

Yandere Simulator starts development in 2012

Osana is released, 6 years later in 2020

Amai is released in 2024, 4 years later (poor quality by the looks of it)

Optimistically assuming the gap will be 4 years rather than the 6 years it took for Osana to come out, the game will be finished in the 2050s. Yandev will be in his 60s!!!

I swear yandev said after the first rival that rivals afterwards would be much quicker since all the code and shit required is already there? But Osana took 6 years to be made, and Amai took 4. That's only 2 less years. And in those 4 years its not like there was any new substantial features or upgrades added like drive to murder elimination method, joining student council, joining bullies etc. Sure 1980s mode got added and from what I've played its fun, but its very barebones and the rivals are copy pastes of each other for the most part.

All he really needs for the other rivals is assets, models, voices etc. The rest of the stuff is already in the game.
