Absolutely great!
The only thing I didn't liked about it - vivid red background behind Elecbyte logo, which means I liked everything else!
Cool art style, all needed bots are present in roster, even guest character, Mazinger
Talking about Mazinger, I wonder, can you add him animation from PSP game Super Robot Taizen Z2? It's game with most cool animations for him(and music, to my taste). I think anim. where Koji turns energy output to MAX before using Breast Fire will look great. Just a thought.
And I think it will be cool to hear Leon - Transformers while game is loading. If possible and you want that of course.
But really, the game is very promising, full version will be must have
