Release Notes: This release fixes an annoying bug with the scoring. In some situations, scoring multiples of 100 points did not give you an extra life.
Release Notes: The game-over animation was improved and the gameplay received a small update. It is now possible to gain points for each enemy object you kill.
Release Notes: The sidebar now shows a graphical meter which displays the time remaining on the player's shield. The animation of the game is greatly improved; it's now related to the tick-count of the machine it's running upon, meaning that it is no longer incredibly difficult to play on faster machines. There is now a minor animation to view when the game is over.
