I like that you made these three beautiful environments to visit, even if the reason for visiting them was so simple. Nice work on setting everything up, from loading level to each level, it all loaded smoothly and managed a decent frame rate throughout.
As the only interaction required being beneath the falling objects, and you couldn't move very quickly, I found myself looking straight up more than was comfortable, so I'd caution against 'looking up' as a core mechanic for interactions.
The ever-present spawning sound conflicted with the serenity of the environments, but that's a minor quibble in the grand scheme of things.
One suggestion, maybe make the jumping a bit higher and/or lower gravity? That could add a fun locomotion mechanic while we collect our falling items of love?
Nice cloud level, too. (I'm using the same HDRI in mine, it's such a gorgeous Skybox). Nice job making a multi-level game for us to play!
