These versions made for the flip phones are only skeletons of the real games. Awful controls as expected, missing elements, strange enemy alterations and overall horrid design is a heavy rain cloud over the NES counterparts. Nothing works like you’ve come to except over the years, and the games suffer from constant audio issues. The biggest issue however is you playing these games. They don’t need to exist. Play Snake instead.
The overall score is the average of all the games:
Mega Man 1 – 0.8
Mega Man 2 – 0.4
Mega Man 3 – 0.1
