It was unclear that you had to spam jump to get up to the platforms at first (I only finally tried once it was clear you couldn't get up any other way).
Something in the level logic might be messed up... I killed the big goon 1x time, but only the robots on the time I finished the level. not sure if I only had to kill the robots or if it remembered me killing the big goon from a prior round and made a mistake there.
Given the weakness of animation, I would have liked to see the combat character arena character to have a small amount of animation, even if it was only a few key frame poses to go along with their actions.
The cut scenes were longer then I would have liked given the amount of game play (It felt like there was more cut scene then gameplay).
Music style is very unique and interesting.
