The App Store is shit for discoverability - and I suspect the lack of an easy keyboard makes it even worse on Apple TV.

But even if the discoverability were top notch, this still wouldn't be discoverable. Does author seriously expect a properly functioning app discovery engine to prominently surface a dice roller, or a gif browser?

There are many, many legitimate complaints against the App Store model and how tough it is to survive as an app developer within that ecosystem, but the base requirement is still "building something good that people want", and I really don't feel like the author did that.
