According to ESRB, this game contains: Violence
Parents might be worried because there's a lot of shooting in this game. But there is no blood or gore at all, and the cel-shading gives everything a cartoonish look.
Mega Man: Battle Network fans probably should be aware that this game is completely different from the GBA titles. It's a very short action platformer much like the old Mega Man games on the NES. Oddly, there's no GBA connectivity feature either.
Deaf and Hard of Hearing gamers won't have any difficulty playing this game. The game's dialogue is all in Japanese, so all cut-scenes have English subtitles. None of the levels seem to require hearing to navigate.
