Game Elements
Bio‑Blocks 
Solid obstacles but the main action is to push them to throw them away. The coolest thing is that blocks can crush viruses if throwed to them. If the block cannot move, it will crumble down. Advice: "Do not destroy too many blocks or you'll be vulnerable to viruses movement". The viruses may destroy randomly a lot of blocks in their wandering and let you be vulnerable to them. As little compensation the barriers generate blocks beside them randomly at a slow rate.
Antibiotics 
The antibiotics move like Bio-Blocks, crushing viruses in their path, but the
best feature is to align them horizontally
or
vertically to get the Big Bonus
(up to 10.000 points) and stun all viruses in the
stage.
Barriers 
The barriers are the four sides of the stage. You can push them to stun viruses and temporarily release special enzima that slows down viruses. The stimulated barrier becomes unactive for 7 seconds before using it again.
DNA Bonuse 
Hidden bonus behind one random Bio-Block for each stage. The DNA bonus appears only when the Bio-Block that contains it is destroyed. The effect of the DNA bonus is to calm down all viruses that are seeking you in that moment.
