Freaking awesome game. I absolutely love the low resolution graphics, along with the simple platformer design. It brought me back to my old days when I would play Ocarina of Time The music mixes perfectly with the atmosphere and lighting and it just makes me feel so nostalgic.
Best feel-good platformer ever.
But I'd rather the game end at 50 fireflies, so people would want to ask for more games like this, rather than use up a bunch of time on one.
