Echoes
An interesting search on games like Geometry Wars gave me the result of Echoes, a free PC game inspired by classic shooters such as Asteroids. Essentially, you’re piloting a space ship that shoots projectile to destroy hostile objects that come your way as the levels progress through harder waves. Graphics and audio are decent for a game of this size, which isn’t to say that you won’t be playing it over and over again. The whole experience is dynamic and brief to the point, which allows you to progress through waves without loading screens or annoying confirm windows. More standard features include a highscore table as well as difficulty options, but the real fun is the unlockable mini-game that is to be had if you can figure out how to obtain an astronomical score of course.
