Great work! Loved the style and gameplay. I do think the power ups are a bit too uncommon. My first playthrough I didn't even know there were other gun types until I got one on wave 7. Lots of juice which all worked well but I do thinks it's missing a more visible hit confirmation. A flash or something one the enemy when a bullet hits them to let the player know that it connected and took damage. It's not a major deal just felt like something was missing. Overall fantastic work.
