This game is strangely addictive. I've got an Xbox and a PS4 in the house yet my whole family have just spent about two hours playing this. My daughters currently ruined things by getting a high score of 29, I can't even get close to that :(
The only downside I found was that initially it took a while to recognise the ramps, but once you've got your head around it, you'll know how to do them.
It's a decent enough idea for a game, but the execution is sloppy. I was expecting this to be more akin to Marble Madness, where the ball has inertia and momentum, but not so - it turns on a dime which means it's less of a game of skill and more a game of "press the buttons at the right time."
