thanks for playing and for the feedback!! 

I wanted to add some simple power ups and more interactive features, but ran out of time, so maybe in the future! Also I definitely get what you mean with the spawning patterns! I tried randomizing the spawning locations for each wave, but it could really be a lot more fluid and random to not make it feel the same! This was my first game, so I'm not too sure if I want to flesh it out into more of a complete game yet, but thanks for your review and your time!! <3
