I stayed on task this time!
What's new?
Ball Pit is more like its own level now. It's got a slide, and more balls, and the pit now looks more like an inflatable kiddie pool than a box. More absorbable stuff with some more variety (desks, stools, light bulbs...), to the point where it should be feasible to pick up all the "Wish Orbs." It's also in a room, with textures, rather than a featureless plane floating in a strange void.
The level select room should look more like a room and less like a box with featureless boxes as 'furniture', too. The music also starts at a random time, instead of playing from the start.
Green/Clone magic should be a little slower, too, instead of being so fast you can hardly see it when lazily waving your hand around.
What's next?
The ball pit level probably needs a little more stuff and variety still. Maybe a little more sound design is also in the cards. I also need to look into some smart activation/deactivation of colliders to make it so that you can feasibly have more enemies on the field, rather than being limited to a couple dozen.
