The game was pretty good, right up until I got to the boss on Level 10. And then it all went down hill from there.
As Blue, you cannot ALWAYS create a blue block for the monster to hit, and so the hesitation and button pounding inevitably lead to death, because he wont freakin' make a block.
Then as Blue, if you move, jump, or change colors -- the monster STOPS his attack and leaves. So I literally got him to hit the block three times. Only. And all in different lives.
Life 1 - Hit hit the block and I couldn't switch to red in time to hit him. He went mobile WAY too fast.
Life 2 - I died after hitting him with the red guy, because as I hit him, a black tentacle magically appeared behind me and hit me.
Life 3 - He went mobile too fast again and then blobbed me.
Keep in mind, I've died over 30 times in just this level alone. The others were a cinch. Between his speed and the glitchy Blue-man, I'm done wasting my time on this game.
