Olaf Bros World

You move Olaf with the arrow keys, running and jumping across platforms. The main objective is to reach the flagpole, but you'll also collect coins scattered along the path. Enemies like Goombas patrol the stages, and you typically jump on them to defeat them. The pacing is quick, and the difficulty can spike in later levels with tighter platforming sections. It feels like a direct, uncomplicated homage to the games that inspired it.
