I did not think about the fact that the red circles would look like red blood cells. I work in a microbiology lab and the enemies were supposed to represent Gram Negative Bacilli (bacteria) but I do see how those would be very easily interpreted as a red blood cell. I will work on making the enemies more distinguishable. I will also look into the getting stuck issue. I had that happen to me once too and I'm not sure what caused it. Thank you for the feedback this is the very first game I have ever made so it is really helpful.
