Well, 3GB was quite a lot to download, and i'm not sure the ultra realistic visuals were necessary, though it makes the game pretty.
I don't have much to say about the game, it was fun, but a bit short.
I didn't really understand how it fit the theme, until I looked at the submission page.
There is a lack of indications as to what can and can't be shrunk, but it never got too much of a problem.
And I laughed a lot because of the music. Like, calm down orchestra, I'm putting rocks in the trash, not fighting thanos.
So, overall, pretty good, though I'd like a longer and a bit uglier game rather than having something that big for only three short levels.
