Huh, I realized that I haven't posted a comment here.
Anyways, first of all, I love this game so much! So many ships from many games to choose from! As someone said, this is like the Super Smash Bros. of shmups. Second, I love the ability to customize everything like alternate skins for some ships, changing bullet colors, different boss warning styles to choose from, and my favorite feature of all, music mods! third, the game is very accessible to all levels of players! Easy or Novice is easy, but it isn't too easy to make the game boring! But man Normal onwards will definitely test your skills! Lastly, I love the scoring system so much!
Also, I am planning to make a review video of this game to not only give my honest opinions, but also to share this game to many people!
