Cool take on the theme Unseen with microbes! I cleared it with 199 score :D
I really like the creative idea of having different layers of zoom! The UI and gameplay was intuitive. in the earlier levels I was getting complacent about having more lives than the max threshold, but this quickly went away in the higher levels where collisions were unavoidable.
The SFX was useful in providing feedback on collisions, and the golden arrows were a nice touch (else i would have been completely lost in the huge petridish)
Solid entry!!
