Bill & Ted's Excellent Game Boy Adventure

Rufus, a man from the future, grants them a device for time-travelling and so they visit the past to bring historical figures into their own time.

This is a single-screen platformer reminiscent of Jumpman .

In each level, the goal is to collect a few flashing objects and reach the exit (which is hidden until everything is collected).

Of course there are various challenges to master first: platforming (complicated by obstacles like conveyor belts or disappearing platforms) and avoiding enemies with different behaviour patterns.

Power-ups like temporary invulnerability or balloons to reach higher platforms can be activated at will after they have been collected.

There are overall 50 levels (divided into ten time zones) to visit.
