3D Animated Rollercoaster in Excel (2011)

To this day, there's a flash game I downloaded from some random site (Japanese/Chinese/Korean, I honestly don't remember) that was sort of like a javelin toss contest, only instead it involved seeing how far you could launch a male student after hitting him with a bike. There were various anime helper summons that could give him an additional push if his momentum was starting to run out. I put an insane amount of time into that game back in the day, but since it was in a foreign language I didn't know the title and could never track it down. Plus whatever flash-drive/laptop I had it saved onto from 2006 has long since bit the dust.
