Simon built this Tetris game in one day on Wednesday. He didn’t use any libraries. The code largely comes from a Meth Meth Method video tutorial, but Simon made it object oriented and adjusted some parameters.
You increase your score for every row that’s fully populated. However, if you have four rows that are almost fully populated and you get them fully populated at once, you increase your level.
