Dragon

Very lag when the dragon casts several blasts of the dragon.
When there are many Dragon Balls next to each other, the fps of the game is only 2 to 4, this happens when I go to face the dragon in the end, he casts so many bumps that my game gets so slow that I can not even move . Samsung galaxy j3. 1.5GB of RAM. This also happens when more than 4 dragon-breathing potions are played.
