The game was quite confusing for me. There were some instructions for the game in the world, but it was difficult to read at times because of the terrain. It seemed like you could switch between healing and damaging, but I didn't see any instructions in the game. I am also not sure what the floating green balls are. I somehow got the infection down from 2% to 0%, but this didn't change anything. The game was also kinda laggy for me.
