Creation by fans of the game.

It’s a decent game description, but it doesn’t quite qualify as a review; it’s more like a simple description. A brief comment on the graphics and sound isn’t enough to elevate it to the level of a review. You write quite well, but in some places, I would use different phrasing. For example:

There is also a “hire hero” button, which, surprisingly, allows you to hire new heroes.

Instead of “absurd,” “banal” or “paradoxical” would be a better fit. What’s absurd about a “hire hero” button allowing you to hire a hero?
