Rockman7-FC is a demake of MegaMan 7 for SNES. All the game’s graphics is in 8-bit pixellated style, re-worked levels to be on an NES scale, re-worked the feel and the gameplay to that of the NES titles, and even “chiptune” versions of the music that sound like something fresh out of an NES speaker.
A free to play ARPG with classic design sense meets fast-paced action, inspired by Japanese themes and the Red Riding Hood tale. Currently in Open Beta. Okami meets Diablo..
