I'm sorry to be a bit harsh, but I don't really think this fits the jam. It doesn't have Kaiju at all, and seeing as you submitted it just a day after the jam opened, I find it a bit hard to believe this was done within the jam time, or was even done FOR the jam.
Also, you're pretty clearly using third party music, the minecraft theme.
That said, it's not a bad prototype. It's functional, and has an interesting graphical style but please, for the sake of those of us who are here for this game jam, don't go around submitting your work to random game jams. It's rude and inconsiderate.
