Hello!

It's been a while since I updated Immune System TD.  I created a glitch where sometimes the enemies don't spawn at the beginning of the level. It was so difficult to fix, I had to scrap a lot of the code and re-write it. The game is  back to where it was, minus a few features:

-Eosinophil and Parasite level diabled

-Ability to place cells disabled

However, there's been a lot of improvements! These are the new features in this update:

-Ability to immediately replay a level when you lose

-Level selection screen allows you to replay any unlocked level

-Game difficulty decrease (previously,players were getting stuck on level 2)

-More scientifically accurate depiction of B and T cells

-Made click-and-drag mechanic of placing cells more intuitive

-Added killer T cells

-More scientifically accurate depiction of B  cells and antibodies

                   -Different types of plasma cells produce different antibodies

                   -T cells are not only able to attack antibody-covered cells, instead, cells covered in antibodies speed up the phagocytosis process of macrophages and neutrohphils

-More scientifically accurate depiction of viruses:

                        -virus infected cells now have a time delay before they explode

                        -viruses coated in antibodies are unable to invade cells and "die" after a bit of time

                         -red blood cells have been replaced by skin cells, as red blood cells have no nucleus and cannot be invaded by viruses

-Main menu now has moving bacteria and white blood cells autospawning and fighting in the background

Future goals:

-Add cancer (Credit to Aeratril Studio for the beautiful cancer cell animation)

-Add sandbox mode
