That's cool. I played half of the first one before accidentally losing all my data from my switch from the 3DS to the New 3DS. It's really fun and it reminds me of Mega Man. Actually, it reminds me of Mega Man Zero for the GBA. I might get this just so I can finish the game.
I do recommend playing it, specially if you like the megaman series or fast side scrolling shooters (like classic metriod), but I really wish it was dubbed so I could play and listen what is being said.
