Phineas and Ferb: underworld adventure

You control Phineas, navigating a series of underground caves. The moment to moment play involves running and jumping across platforms, avoiding environmental hazards like pits or steam vents. Your main objective is to collect a set of colored orbs scattered through each stage to unlock the exit. The controls are basic, using the arrow keys and a jump button, and the levels are relatively short. The pacing is steady, without being overly difficult, making it suitable for a quick session. It feels like a light, uncomplicated platformer built for fans of the series.
