This would have been so good if only:
1- controls weren't so hard. It's very difficult to position the magnets precisely, a slight change in position and the vector goes to the other side;
2- The reset button actually reseted the level. Instead, points keep going down and if you want to try a high score, you have to exit to the menu;
3- There was a retry button after each level in case you want to try and improve your score;
4- There weren't glitches in which rockets explode for no reason middair (happened a couple of times and I had to reload the page to continue playing);
Still, very nice game.
