Yorbie: Episode One

For this trophy I suggest level 3, "Down the Drain". The reason I suggest this level is that it seems to be almost impossible to beat the first two levels on Insane without at least dying once, due to the turret section at the end of each of these levels. You are basically stuck in a turret and take relatively heavy damage for the duration of your fight with flying robots. I've personally attempted this multiple times on the first two levels with no success, specifically because of this final section. The third level lacks this section, and so it's simply a matter of memorizing the enemy layout for the level and making it across all of the platforming sections.

This is no easy task, and it may be possible on the first level with perfect accuracy against the miniboss at the end, so give that a try, and failing that go to the third stage.
