I find it really impressive that you have created a 3d game in just one month!
I also like the customization feature.
Gameplay-wise I have some suggestions though. I'd like it if there were a bit more acceleration and deceleration in the character movement, like this it felt a little stiff for me, keeping in mind you're essentially controlling a beyblade kind of object. That's also my second thing to criticize a little, maybe it was just my way of playing it, but I felt the fact that you're a beyblade battling against another, which sits in a mech kind of thing as a bss (at least I interpret it like this) and no way to battle the two beyblades directly against each other felt like the choise for the "characters" is a little underutilized. I didn't really feel like there's a specific reason why my character could'nt have been any other spinning thing, sorry.
But overall good work, definately a lot of work for one month!
