Untitled Semester 2 2D shooter (catchy)

A 2D Top-down Shooter inspired by the classic Treyarch COD Zombies. There is a shop with a clear upgrade path, armor, 20 waves with the enemies getting increasingly difficult, and even a Jukebox with some great copyright-free rock songs. The game has just entered 1.0!! so if there are problems please leave them in the comments below. This is my first (finished) Unity game and hopefully the start of many more! Thanks and I hope you enjoy it!
