So some things to note, sacrificing sleep in the name of making games is never a good idea if you doing it as your job, but as a hobby or for school grades, I have done it a lot.
when your brain is sleep deprived you will start programming even worse than normal, so be prepared!
When I’m sleep deprived I start writing method variables like
int void float bool isTrue; for example.
I also will not sleep for Day 6 as I want to do my best work!
