The Fly will have the ability to inject a virus to blocklanders thus infecting them with a virus called
Blockreia (Or another good name somebody can think of)
Positive effects:
You live!
You have 100 extra hp!
You slowly die painfully!*
Negative effects:
You move slower
You cannot jump
You cannot hurt someone
You live forever!**
*Just a note, I crossed it out because I actually didn't want to worry people about this serious infection, i mean, in this game called Blockland, you respawn quickly, so what is the point?
**You can still be killed by these weapons and anything that is more advanced than it:
Gun
Spear
Sword
Bow
Hammer
Wrench
Printer
Skis
