What programming languages should I learn to be a game dev?

Hello devs, I am actually new to programming, so I only learnt Java and C++. However, I found out that I desire to become a game developer, but I do not know how to start. I want to start from the basic ones to the harder ones (BTW, I have used Scratch before). My goal is to make at least one game each day from now on, from easy to hard(so it will gradually become a few days per game or more). I do not mind hard work and because it is summer, I can have more time on this. Therefore, what do you recommend me to start first and then afterwards?
