I think this is a pretty neat concept!
I did have some pretty big issues with playing it, though - I'm using Windows and I don't think it worked as it should - the enemy didn't seem to die after its health was depleted, and shot a lot of slow-moving bullets at me in a short succession, which didn't seem to harm me either. I think it could be a decent idea to see if you can get the build working if you're also using a Windows device? ...it's a bit difficult to play at the moment, sadly.
It'd be nice to see it working since I do think mixing and bouncing the lasers is a very cool way of doing combat!
