I like it, and despite being so simple, it does feel really unique.  I think it would have been neat if the game really took place in 1 dimension (that is, stabilize the white line).  The way it works now gets hard on the eyes for its strobe-like effect (though it is a pretty neat aesthetic if you don't have epilepsy).

interesting idea but its not really playable, things keep spawning on top of me or too close for me to get a look at them before they get me

Nice Idea, but the gameplay loop is kinda broken, as the viewable area is really small (i know it's what makes the game) and it took me some to find out, that I can't just click and hold to autofire, as the wripple effect keeps repeating but the bullets don't. With some small tweaks it would have been really great. Keep it up!
