Get to know about the game Square Man
A long time ago, around 2007, people played something called Squareman on computer websites by using just their arrow keys. The character you controlled was a little stick figure shaped like a square, and your job was to press the arrows up and down left and right to move it from one place to the next.
The goal of playing was simple: keep moving forward until you saw that checkered flag finish line. There were things in the game, like tricky red spikes or pits, you had steer clear of by carefully jumping over them when they appeared.
Some players found Squareman a bit challenging because sometimes it felt awkward to get just the right jump in time. The enemies also tended to come pretty speedy and dash into confined spots that required precise navigating to avoid. Even though Squareman itself was easy to understand starting, it often meant keeping at it many times, failing repeatedly but wanting eventually succeeded.
