Great art, but the controls need some polish.
The story, animations, art, and sounds are great. However, the controls could use some polish. The controls when in the immune system are quite touchy. Takes a bit of time to get used to. I honestly expected to control the remedy with the mouse. Also, for the jump, it shouldn't fire again until after the key up event (easy -use a boolean). This would keep it with normal platforming standards. I know for myself, I tend to hold the jump button until I land. And lastly, the run animation could be perceived as cute, but because it seems to only be 2 frames, it doesn't seem like an intentional design choice but more of a choice out of laziness. But lets be honest, Im nitpicking. The game was fun and enjoyable. Good job.
