It took a minute for it to load, but it played with no problem on my Mac. I was able to move 4 directions and shoot with no problem. I killed over 100 human but they still kept coming so I let them take my planet. I probably would have kept fighting if there were different enemies or milestone achievements. All in all I think it is solid game for the jam. I liked how the humans were the invaders and that the rounds were large instead of tiny.
