yikes, do you not realize how hard it is to make an entire game on your own with your own assets? Especially one that has its own unique art style like this one.
The bigger a game gets, the longer it is to update too since you have to come up with new ideas that fit with previous ones and you also have to make sure the new stuff you add doesn't create any bugs with old features.
If you are among the very few people who are talented enough at game design, programming and art to make stuff like this in a few weeks (while also taking care of yourself) then congrats, you're one of the most talented people on earth, but you're also just proving the stereotype of insanely talented people being arrogant jerks who look down on others
