Get ready for a boss run everyone, because Robotnik's revenge is exactly that. This hack includes all the boss battles from not only Sonic the Hedgehog 2, but also it's predecessor, Sonic the Hedgehog as well!

The game controls just like Sonic 2, with the option to play as sonic or tails. As you progress the games order of bosses will be a sonic 2 boss, then a sonic 1 boss. It's set in the Death Egg, with various texture and level alterations to fit the style of the Death Egg as well as the mechanics of the boss fights.

There are also two modes:
 Time Attack: a mode in which your goal is to get the shortest amount of time. For every boss you defeat you get three rings.
Survival: Essentially the same as time attack, except you don't have any rings, providing an extra challenge.

I recommend this game to anyone who wants a challenge.

Even though this review has passed 100 words, it's still not a full-fledged review. I recommend wording your thoughts and feelings on this game a bit more, rather than just putting down a short sentence. Also, try putting your ratings in the review, so people can easily read it. 

Being over 100 words does qualify to be a review, but I think you can work on a whole lot into your reviews.
