All very good points, and admittedly all things I wanted to do but didn't get around to! The original idea was to have the player start small, picking up relatively tiny objects, then growing and picking up larger objects as they accumulate mass. The camera would zoom out and the player's collider would grow as the tornado grew in scale to reflect the change in size/power. Fuumiko's features would have also changed as you gain strength, including a rampaging face and higher tornado segment count/rotation speeds.
I should have focused on those gameplay mechanics early on but I hopped over to art and shader work a little too early ('-_-). Some of those features are still technically in the game's assets in the form of unused code and texture work.
