Damn, that was a super fun game! The controls are super weird at first, it's so hard to get used to the fact that the bacteria you control doesn't follow your mouse cursor one to one, but it was weird enough to compel me to get good at it! I eventually defeated the white blood cell (and turned it good?) and I had a blast doing that! The game might be a little too hard for your average player, but as someone who enjoys shmups and bullet hell games, I had a blast! For the first game, this was amazing, you did a great job!
