Hi! I played three times. The first run was really hard - I wasn’t getting anywhere, just blasting those nasty fat cells before they destroyed me pretty quickly. The worst offenders were the smallest ones, since they’re so hard to aim at!
On the second run, I tried to find the heart. I heard it beating somewhere but only saw the big red walls… and again, the fat cells killed me.
On the third run, I realized those red walls WERE the heart! That was a nice moment of clarity, hehe!
Overall, the game is pretty fun but kinda hard for me. What I loved is the science and medicine behind it - all the cells, and how we’re fighting a real disease! That’s cool in my book!
