Very fun game! I did also get a little lost on the planets as I was walking around but a beam of light sure does sound like it would fit into these theme of the game!
Overall I found it very fun to travel between the different planets and collect different species :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
