Well, it's definitely a perfectly serviceable game. It's not too hard to get to 25,000 meters with almost all of the upgrades (I had 8/10/10 when I got to that point). The trick is in waiting 'til the last second to use any of your mid-air smashes.
If you hadn't said it was based on some sort of memes from H3H3, I would've been content to believe it was its own standalone mini-game.
