You don't KNOW whats hard.
Until you play the remixed levels in Bit.Trip Beat fot iDevices, it is the hardest thing you will ever see, pick it up now for 0.99, you will never end normal mode, you will never end remix mode.
The first 4 Megaman games are tough! I still can't beat them! But I have to say, there are two games that make me angry:
-Castlevania: Circle of the Moon. This game has impossible enemies, and even worse hygiene. I feel dirty after playing it (hurts so good!).
- Jet Force Gemini. As fun as it is, it wasn't exactly easy when I was 10, and today it still holds a degree of challenge for me. Still, when you die, the game makes the most DEPRESSINGLY HOPLESS MUSIC KNOWN TO MAN! But it still has my favorite soundtrack ever.
I know the Konami Code, but tgat only somewhat eases it. Remember, one hit kills you and everything in the damn level is doing its part in making sure you don`t get out.
Great game, though.
