Hope it's not just me but it's really hard to hit the aliens, either my computer is a bit laggy, the aliens are too small or the hit radius is too small (doubt it!) Maybe if you could change it so the aliens are easier to hit or if something else could happen that would be great! :) Great game but this just makes it a bit too hard to play and progress!
Thanks if can fix it or if someone gives me a solution to make it easier to hit the aliens!
