This is actually pretty cool. I will say though, with such a small area it makes it a bit awkward to play. And all of the enemies come from the same spot. If there was something like a staircase that more enemies could spawn from it would make it a bit more challenging. Another big change that could be added to the game is to make a map similar to some of the big super smash bros. maps. It would be very fun and a game that could probably last for like 5 sequels.
