MegaMan 2

I finished playing MegaMan 2 (Easy Mode) on NES Classic Mini (2016)
Here's some useful info Password Generator
It's pretty much accurate Pwd Gen.
Although it raised some question for me. Like how many lives can you have?
Probably 99.
You can have maximum of 4 Energy Tanks. As always don't forget to write down your passwords and compare it with pwd gen and use them only if you need to.
MetalMan has powerful weapon don't forget to use it.
You can shoot Metal Blade diagonally. Up and right...you get the idea... 8 directions
After you beat all 8 robots there are no more passwords. You'll have to be very careful to get to Dr.Wily.
Refill energies as much as you can by destroying easy enemies, you'll need it.
Tricky part is lenses that shoot you. You don't need to break every wall with CrashMan's weapon.
Every robot has weak spot.
Alien's weakness is Bubble Lead. Escape his shootings and when he gets close to MegaMan use one Bubble Lead at the time.
He's vunerable after every three shoots. You'll have to jump around to escape pellets.
Don't use any other weapon on him because he replenishes energy by apsorbing.

I first finished FlashMan
then QuickMan
then MetalMan
then WoodMan
then BubbleMan
then HeatMan
then AirMan
then CrashMan

this is mine exact order.
