Nintendolife gives Mighty Switch Force a 9/10( 5.99 on eshop) and Swapnote available!

I've downloaded both of them, SwapNote (Letterbox) is pretty good but it needs improving because you can only reply once to a message. =/
Mighty Switch Force is great but it's more of a puzzel game rather than a pure shooting paltformer like Mega Man.
