I felt like this was a great concept, but the execution was lacking. I love this series, but this game wasn't as entertaining as the others. I felt there was no purpose for the body bubbles besides aesthetics; this sheer amount of enemy firepower encouraged mobility, and class 1 size bubbles were infinitely more capable than larger sizes. Give the player more reason to customize with different weapons, with more unique enemies that make specific weapons less effective. The body bubbles should also have more purpose, like boosts to speed, defense, attack, etc. Personally, I breezed thru every level using 3 5spread guns side by side, class 1, no body bubbles. Just strafe around the edges and you'll hit practically everything. But I have high hopes for a sequel to this game. =]
