I was watching the funbase alpha stream when they played this, and my feedback pretty much aligns with theirs.
I understand what you were going for with the spaceships shooting lasers at random speeds, but since you can't react in time to the lasers, it feels random whether you'll make it past them or not. I would either include some kind of indicator that can telegraph when or how the spaceships will fire, or have them all fire from farther away and fire slower bullets so players can react to them in time.
However, I think the game has a nice visual charm to it. And for your first game this is a great job! Nice work.
