Even though I understand Portuguese, I think it's better if you guys upload it in English, since this is an American website!
Apart from that, the game is not that bad for a few minutes, but it gets boring and repetitive pretty quickly, and the hit detection is odd, too.
Overall, I think this game has much to improve if you make some more levels, game modes, different kinds of balls and movements! (And improve the hitboxes greatly)
The game seems nice... but please, make it international-friendly, write in english would make it readable and playable for more users, i could only play by luck, other than that okay game.
