Great little multiplayer "flappy bird" arcade-y combat experience. The only thing that was a little annoying were the death noises... mainly because we experienced far too many of them XD.
Jokes aside, this really is a great little game. I'd love to see it expanded upon a bit... maybe add a basic AI for singleplayer mode or something, if it's requested often enough?
The level designs are pretty cool too. In short, it's a nice game good for a little while of play with a friend. Very enjoyable, I'd recommend it wholeheartedly.
