ジオメトリーダッシュ・サブゼロ

A variant of the Geometry Dash series. The game is played by jumping and avoiding obstacles that appear as the screen scrolls by. Once you get to the point where you've played it so many times that you can just move the controls along with the background music, then it's almost soothing. But that's a looong way to go and it takes time. If rhythm games aren't your thing, you'll probably have a hard time playing this. Once you get the hang of it, you'll feel a sense of unparalleled immersion, so don't lose heart and just keep going at it. It's totally worth it.
