This game is super fun, I didn't expect much but the monsters make it way more exciting than normal brick breakers. You have to dodge their attacks while keeping the ball going, it keeps your brain busy. I love the stadium gauntlet mode, feels like you're in a real kaiju battle arena. Power-ups are balanced, sometimes you get huge paddles or multi-ball which helps a lot against tough kaiju. Only thing is, no online co-op, but local two player is fine for couch play. Looks and sounds exactly like NES, which I wanted. Paid full price last year for the cart, now I get Steam version for almost nothing. Good deal. Everyone who likes retro games should try the demo at least.
