For insane mode the stats Defense and Agility are the most important to have points invested in. This is because the enemies are strong and agile, you definitely want to counter this.
The Strength and Magic stats are for damaging your opponent and are less important because a hit means experience points, so low attack stats should get you more exp.
There are a couple ways to juggle but the most basic combo is this:
- □ □ △ (in air against AI) Square + Square + Triangle
- □ □ △ △ (in air against AI) Square + Square + Triangle + Triangle
To juggle middleweight enemies you can do this (this combo also let's you hover in the air indefinitely):
- □ △ △ (in air) Square + Triangle + Triangle
Remember, not all enemies can be easily juggled. Only the lightweight are relatively easy to juggle. Middleweight enemies can be juggled using the combo above but heavyweights + most of the beefy enemies require advanced juggles.
There is also an "easy" way to defeat some levels on insane mode:
- Arrow spamming (need full agility stat)
- Skipping levels (need other player who already beat it and can only be done on certain levels, mostly non-boss levels)
A final tip: There is always ONE enemy that actively follows you around, try to focus on this enemy.
