Glad you finally fixed this, it's one of the first games I'd seen but only now have I been able to get around to playing it. 

A bit buggy, but I think this is probably one of the "longest" games from the jam I've rated so far. While having some length is good, sometimes it felt like levels were very big and disorganized, a wider camera or map could have made the game a lot more enjoyable. The invincibility power-up was a nice addition, although unreliable as sometimes germs would cover an entire platform and you might not get any vaccines.

The game-balance could use reworking but otherwise I think it was fun, nice job!
