After 3 years of playing a pirated rom, I bought the NES box set and couldn't be happier. The game itself is insanely fun, seriously probably my favourite retro-style game and easily my favourite NES game. Just as Mario is about just one move (the jump), Micro Mages is also designed entirely around one move: the wall jump. You scale vertical levels and it feels amazing; if you're close to the bottom it scrolls slower, allowing for a slower pace, but if you've mastered the game, you can go up super fast and the screen will scroll accordingly. It's super replayable too; can't tell you how many times I've turned it on and played through the first three worlds. It never gets old! The game is extremely fluid and well designed. The bosses feel awesome to take down too, with fun patterns. EXTREMELY fun in multiplayer (my go-to multiplayer game). And the physical version has so much care put into it. The box is the exact dimensions of a regular NES box so it fits right in with my other NES games. I cannot recommend it enough. This game is so, so special, please give it a try.
