Hmm...
This has potential to be a really good game. Just makes sure you do theses things and im pretty sure it would be incredibly better.
*Your graphics need to be way better. If you could make an actual character instead of a ball, it would totally own. The animations were good, so if you need a graphic designer, I'm sure somebody will be willing to help.
*Make sure you add sound fx, but you dont want them to dominate the music or the game.
*When you make the character, give him more to do. like when you press a button, punches the crap out of the robot in sequence. (Kind of like Good of war)
*Speaking of the game, keep the buttons closer together. It was kind of hard moving from A to B.
*Make a more open and creative backdrop. I would help you, but im already busy as it is!
Thats about all I got right now. OH and when you make the character do something awesome, make it interesting by zooming in and out on his actions.
Hope this helped. Sorry for having to review this with such a low number.
