I have the passwords in a text file, which is read into a two-dimensional array of char. I was going to use an array of strings but I had to read the player's input character by character. So that was an array of char and it was easier to just cycle through each password and check each letter explicitly (passwords are only five letters long).
After typing in their password, the player presses enter and it will either clear the password they put in (if its invalid) or start the correct level.
Tomorrow, I'll start on either the level transitions (I didn't put these in my original plan so I don't really know what I want them to contain - I'll need to brainstorm). Or the high scores depending on what mood I'm in. Then, after that, it's just powerups (will take a while) and sound (finding the right sounds will be the most time consuming I think).
Thanks for reading
