I found this app by googling "How the fuck do I get my code to compile" after fighting my program for hours

Teamate: Hey I'll checkout you're branch to see what you've got done today.
Me: ...Ok.
Few hours later Teammate forgets to change branch and overwrites all my code in my branch causing merge hell and creating hours of more work.
Me:...what in the f***?!

In high school for an assessment we all had to make a simple game and we to plan it first and then program it. In the planning stage we had to list variables and functions used and whatnot I'm my planning sheet I was given I had "variables modified by user" which basically meant data inputted buy the user stored in a variable with only one player name variable listed in it and everything else in my game was being computed another runtime and my CS teacher told me I didn't have enough user inputted variables and I explained that it didn't need any more she said "so you're telling me the user enters their name and the the game just plays itself?!!!
