I like the graphics, they're pretty pretty if you ask me! Although I am completely confused about the goal of the game.  I understand I have to heal the sick but at the start everyone coughs so I assume everyone is always sick? But then I passed the first level not doing anything. And then I tried to heal a few people and apparently I got sick? There is no feedback to the heal action so I don't really know when I heal somebody or when I don't. Also, the controls are a bit wonky. I feel like you tried to make a cool concept but I just can't grasp it :c 

The game looks great, but the controls are too tricky! You should reduce the inertia of the character and use bigger platforms, at least at the beginning until the player has had some time to get accustomed to the movement. Also, make the player jump when the key is pressed instead of when it releases, it feels veryun responsive to have it on release.

The fox sprite is amazing, I love it and it´s animations.

I like the idea but the jumping is weird, I guess you've used the event 'Input.GetKeyUp' For me it eould be better the sensation if you used  'Input.GetKeyDown' with which you activate in the moment of the key is pressed. With all is pretty fun
