User Reviews
Boss Up is a short and fun ride that really comes into it's own as you keep playing! A lot of the bosses and concepts introduced were really cool, and I'd love to see the idea of a boss rush where every boss is a different game genre expanded upon in the future! Keep up the great work!
Very fun game that focuses on hype boss battles with no fluff.
Absolutely fantastic selection of boss fights and weapon choices, as well as great art and music!
I'm out here bossing it, and by it, lets just say my peanits.
There are two types of people, stupid dumb dumb losers and true Boss heads
