Yuu Maze

Overview courtesy of GiantBomb:
'Yuu Maze ("Maze Play", also spelled Youmais according to its title screen) is a single-screen maze game akin to Namco's classic Pac-Man and its many other imitators in that the goal of the game is to drive the futuristic vehicle around a maze collecting dots while avoiding (or temporarily eliminating) the enemies.'

You get to choose either a good (killing the scientist) or bad (letting the guy in front of you die) ending after completing level 51, which is determined by your reflexes at the final cutscene.

I did two playthroughs, one showing off the stages when you take the left door and another where the right door stages are shown. Both endings included at the end of each, despite being literally the same except for the guy standing up who ends up dead or alive as mentioned above. I also triggered a series of bonus stages which are called 'Reverse Rounds', the tunnel that lets you enter to one appears randomly though. There are 20 of these areas in total and are completely optional, but during the first playthrough I managed to show them all.
