The game looks super polished from the gifs so I'll download it which I normally don't do.
Edit: It was worth the download. My critiques are that with weapons like the rpg and sniper, there was a time frame after you shoot them where you couldn't for a while, so it would've been nice to show that "reload" time sort of. There was also a minor bug where it always said you survived 6 waves when you lost. Other than that 5 stars.
