IdeaYour objective in the game is to collect points by making the green balls drop to the hole in the middle. Red balls on the other hand will increase the gauge on the left, and when this gets full, the game's over. With blue balls you can decrease this gauge. With yellow balls you can destroy other balls, and with purple balls you can swap the "charge" of a ball from negative to positive and the other way around.
When a ball collides with another, these may combine depending on "charge" and the type of the ball. This however depends completely on the type of the ball. The features of each ball are explained in detail in README.txt file, included in zip-file.
ControlsUse left and right arrowkeys to change the angle of the highlighted (yellow) ring. With up and down arrowkeys you can change the highlighted ring. With ESC-key you can go to the main menu at any point of the game. You can close the game by pressing ESC-key once more in the main menu.
ScoresThe game uses now Game Jolt highscore- and trophysystem. To get access on these you must have an account on Game Jolt. At the beginning of the game it asks for your username and token, but to play the game these aren't necessary. They're only required to enable highscores and trophies.
