I love the gameplay because you're gonna have a very hard time to pass the level if you don't play it stealthy, so, nice use of the theme! However, I feel that this is a game that you could die a lot, so the fact that you have to return to the main menu and pass through the tutorial every time you die is annoying. I also feel that some graphical elements could use a little bit more detailing, like the germs and the platforms. But overall, it's a fun game!
