The controls are perfectly responsive, however maybe a bit TOO responsive. The slightest tap of a movement key sends you flying in that direction. The movement could be revised, or thew game could be re-uploaded with less a less sensitive ball, along with the other games. Seriously, I know what to do on a certain level, but I keep dying so much on it. I'd say about 50 times, but it feels like a fucking thousand!
All in all, not a bad game, just hard to control the ball to make it fit through tight spaces, even with the 'smaller ball' powerup.
The highly rage-prone (like me) shouldn't play it.
5/10, 3/5.
Take my suggestions, maybe your fans will be happier.
