Huge fan of this game. Like, huge. I was playing it for a while yesterday and I completely forgot it was made for a game jam. The difficulty ramped up, but that's totally to be expected, however a checkpoint would have been nice. After your 3rd, 4th, 5th death you don't really feel like going back and finding all the bananas again and just head straight for the exit. That's honestly my only complaint, and it's very minor.
Audio sounded very authentic, as were the graphics. Gameboy soul was there in spades. Superb submission.
