Very cool visuals and art direction, the gameplay was also simple and fun! I'm glad the combat just resets when you lose, no wasting time going through menus and dialogues... I would love to see the sprites for the characters without the screen filter, all of their designs look sick!
You have a sweet base to build a full fledged game is you put in one more week or so. You can also take it in so many directions. More combat stuff, upgrades for your beyblade, a bit more of story... I see a lot of potential.
I love the vibe for the game. Beyblades, anime and tournaments work so well together don't they? (I did basically the same thing as you did). Big props for having some narrative background for the gameplay! Most people just ignore the story of a game. Good job!
