I have been playing this game for hours and I'm so addicted to it. Its a great game with a great layout. Use can easily play it with just using a mouse and nothing else or the basic keyboard. So you can lay back and just have fun. I also love how it doesn't delete your file so you can keep getting weapons and new upgrades. Its also not the same layout of bosses over and over again. Which is super fun and entertaining. I love it and even the art style as well, with its slightly pixel characters and beautiful background to type it all in. There is no bugs in this games and very entertaining.
