I really like the art style of this, quite simple but it works really well. The main concept is also quite interesting, you have a lot to worry about, which could work in concept, but doesn't work that well when playing this game. I felt like the grey hearts emptied way too fast, and the shooting felt pretty slow and didn't come out of the gun. Enemies kill you really fast and more often than not you don't get a death screen and you need to restart to play again. Also, I don't like the lack of a tutorial. The music is pretty mediocre, and the sounds are way too loud. I'm sorry for being so harsh, but this game has a pretty good idea, but just isn't that well made or fun.
