my longest coding session was from 10am to 2am, so 16hrs
was in first semester of uni and we had to build the game "breakout" using a predefined guideline.
i had to program the collision detection of a ball against some blocks that had to be destroyed
took a long time for me to do the task, as i'm not the fastest coder (and often neither the smartest😅) and had to fight a bunch of bugs too.
in the end it kind of worked but the performance was horrible at best
