That is not virus, that is bacteria. Viruses cannot breed and multiply on their own, and need other organic cells. Bacteria breed like the 'viruses' in this game. Get your biology right :)
The door with spikes on the other side is just hilarious :3 (if anyone doesnt know where it is, when you see the first other human other than yourself, it's the middle door)
I have noticed that when a jet flies by, of the screen shakes, there is sometimes minor lag, and any presses of the jump button in that time don't seem to register, and you just plummet.
I have a few things to improve with this game...
Firstly, why can't you upgrade the recharge time? And why does the amount of charge stay the same until the next day? Can't it charge overnight? Is it solar powered?
Secondly, a game about a massive amount of electricity and no reference to 1.21 GIGAWATTS?! Wow...
Thirdly, when you upgrade capacity or health, why does the bar remain tiny? Can't the bar get any longer to show it?
Here's a note, the Z key is just an unlisted hotkey for a bomb, which you can make with the other menu. Also, shrinking the bomb makes it more powerful, pressing the Down arrow key on the bomb seems to have a compacting effect on the bomb, increasing damage and knockback effect.
