It's an interesting concept. However it's a bit simple, it's "eat to upgrade to eat more to upgrade more". I'm worried about the depth of the idea. Most upgrades tend to either make the circle grow or the pull force grow or catch different type of stars with different colors. The rest are just variations of this but the gameplay itself is more of the same and it gets repetitive very fast. I'm worried it won't get any better than that even with the full version. Still, at least it's short and in less than 10 minutes of gameplay it shows enough to let you decide if you're interested or not.
