The best way to beat that little invisible bastard in the fifth Cave of Trial is to use Magic Cannons and Phoenix Strike as best you can to keep him back.
Explosive glitch happened to me on the last boss. Everything went normally, when all of a sudden instead of him firing one barrel, a stream of barrels came out and each one hit and destroyed my wall.
An epic tale of friendship, love, and meaning. The heroes go on a quest to find answers, and discover that love is the true winner, and that real power comes not from the body, but the heart. I was moved to tears by the powerful narrative and developed characters.
After about 20 minutes of play, I really can't stand this game anymore. It revolves around the boring idea of kill, get stronger, and kill some more. There's a major lack in any key events, other than dull bosses and the addition of a few more enemies.
Also, the easy mode is too easy, and the hard mode is too hard. Difficulty is lazily hiked up a bit by simply upping the amount of health on everyone, which just adds more prolonged, boring gameplay.
And where's the splash damage on the rocket launcher? Shouldn't a few penguins in a cluster all be obliterated by a rocket to the face? I'm giving this 2/5 stars, just for weapon diversity. Everything else? Needs work.
