Released for feedback

I've been working on a very simple, no bells and whistles space shooter.  It is minimalistic in its approach.

There is only you, your weapon, and the "Blergh" aliens.  You need to save earth.

The screen resolution is low by design, the audio is purely programmatic, mimicking games of yore.  The game play is simple, as it is a game I want to be able to play, and let go, after spending hours at work thinking about complicated issues.

Also there is no game engine is used, it is all from scratch WebGL and WebAudio.  This is what keeps me motivated, puzzling through the tech details of these APIs :)

This is not a finished game yet.  But I am "releasing" it, in order to get feedback, and allowing myself to test it on multiple machines, on which I do not have an itch.io account.

Any constructive criticism appreciated.

Remember this is supposed to be a small game, so any ideas, need to fit into a box of smallness.

Now, shoot those "Blergh!!" and enjoy!
