It’s basically just Zero Mission but not fun; it has no flow or ingenuity. I spent at least 10 minutes shooting at every wall and floor in the first room looking for a way to progress. I played about 20 minutes before dismissing it. Don’t download this expecting a full redesign like “metroid deep freeze”; the general layout of the map is the same. This type of rom hack definitely has a certain niche that would enjoy it, but I don’t recommend it to anyone who isn’t intensely obsessed with Zero Mission.
