Those are some great thoughts!
I agree, I’d love to add more enemies, upgrades, and story elements. I am seriously considering making an expanded version of the game if there is enough interest. Adding improving graphics to things like the planet from space (which was really just a placeholder that I didn’t have time to enhance)
I really appreciate your thoughtful feedback. I can tell you put a lot of thought into your comments, and I will seriously consider adding some of those elements.
I have a bunch of ideas for improvements to the game as well including more characters, scenery, puzzles, and possibly a mother ship.
