Very cool. You really nailed the whole feeling of mecha/kaiju, including the sound design. The actual battles themselves were OK (if you're able to figure out and master your current weapon) - it required good reflexes though :)
I encountered a couple of bugs, like Kaiju just waiting for you to slaughter them (near the end of each round) and in one case, controls freezing (couldn't move) but overall, very solid and engaging system!
