I didn't play it, Im gonna talk as a game designer.
First thing I notice, your tittle screen looks great, but, the tittle name isn't matching whole scene, I think you wanted it to look like it was made out of lasers or something, but if I was you I'd change it.
Second, the UI is sticked on the up corner, never do this, you have do leave a space between icon and the screen corner, so always word with grid.
Besides that, I like what I see. Is there a narrative behind the game? it'd let it even immersive, not just shooting for fun.
Great job. Keep it up!
