Astronoid

Description
This game is an unusual remake of arkanoid game. Your goal is to destroy all alien turrets to complete each level. You don't need to always deflect the plasma sphere, but you really need to evade the alien shells and missiles to survive.
There are no time-expirations in the trial version. But only tutorial mission and the first levels of each other missions are available before registration. Full version allows you to create your custom missions.
