How long should it take to write a code for a video game with multiple levels?

Question

average time to spend in project?

Answer 1

It really depends on your skill and your techniques, aka how fast and good you can solve some problems or errors which occur... A professional programmer can make some basic game with multiple levels within a day, and for you, as I don't think that you are that good, can take multiple days, or weeks, depending on how much time you are willing to spend making it
