I have the backer version from Legend of Iya. Playing on normal was pretty hard but I guess that's what you're going for a la classic Mega Man in a way. Is this the full version?
I got to the end of the first jungley stage but couldn't progress and I didn't know why. I had the ray gun and the gravity ring. How do you save? I'm guessing there are save points but didn't find any. It was just frustrating having to kill the enemies just to have them respawn a few seconds later, seemed redundent.
Anyway really gorgeous art as always, will probably try again on the easier mode. Great concept too taking something modern and kind of putting a retro spin on it.
