Despite the movement being a little confusing at first, I found it very fun, as well as beautiful. It reminds me of some old games like Aleste, but infinite. In fact, you published this in 2016, a long time ago... Even so, playing it I wanted to see this game with more things, like music, or even levels. Many of the games I find on itch.io are experiences that I rarely open again, but a game like yours ends up being different and fun because of the randomness, the different weapons, the enemies (Not that other games aren't fun , they just... couldn't entertain me for as long as yours), so it's kind of sad that you stopped there. It seems to have a lot of potential..
