I was given this game to give a preview to my audience and I enjoyed it a lot. If I didn't like the game I would say it. This game does get a bit challenging if you don't upgrade ships and weapons as you get farther in the game. I found the exploration levels, where you go and explore a level is where I had the most fun. The controls feel just right and it wasn't to hard for me to jump in and play. Now I know this is a port of a phone game as well but I think $15 is just right, you get to use a controller and the music and graphics are stunning.
