Cool game! Could this be inspired from the classic invader game? I rather have the shooting be permanently active instead of players having to hold down the mouse button down the whole time. And maybe an indicator what comes after the fifth upgrade. I do love the visuals, a subtle neon glow on the shapes against a pitch black background. A game with an endless goal - depending on player's dodging skill - can be considered timeless! 

Neat & Fun game, The visuals are nice and simple!

It is a start for something! The controls are smooth. It needs a bit of music, particle explosions and bullet patterns. Good work!

Easy, but fun and addictive. Nice!.

Cool, but too simple
