I'm a CS student at UoPeople so if you have any questions, you should let me know. I believe it's pretty good, you can see the textbooks that we use here:

You can check its accreditation here: https://ope.ed.gov/dapip/#/institution-profile/233675

My goals are to improve my existing programming and math skills and receive an accredited degree I can start using on my resume. Ideally, I would like to be able to get a job as a developer for a major video game development company. I also don't have much money to spend so this model looks affordable to me, but I don't know anything about the quality of the courses or wether that selection of courses is the right path for me. Any respectful insight would be helpful.

If you want to get degree for these purposes I recommend western governors university. It is a major US university run by the government.

Nothing against university of the people, but I don’t know how accepted it is.
