This is a nice little game, the art looks really good, the music and sounds fits nicely.
I would say it lacks some feedback to the player, sometimes an alien just pop out of nowhere without any hint of where it wd appear. The ammo count is also misleading, I thought it was scarce, but in reality it never ends.
If you could play it and give me a feedback as well. https://itch.io/jam/beginners-circle-jam-3/rate/795745
