I would consider myself a top down shooter guru. I literally love them. That being said yes this isn't an easy game if you don't come in humble you'll lose. If you don't understand the controls, you'll lose. If you don't understand the mechanics you'll definitely lose. The music is good in my opinion and the graphics are a lot but you have to know what you are looking for and how the enemies are attacking you. Long story short I think this is an underrated game and people judged harshly because the ♥♥♥♥ (skill issue). I recommend this game to seasoned bullet hell players for a fun yet difficult game. I believe in Konami and support their games.
