Even in this form, still one of the most competent completed Kirby fangames ever made. That said, I do have my gripes, though pretty much all of them can easily be chalked up it being such an old game.
Ended up getting a bit too tedious and frustrating for me even with max lives on easy mode, so I gave up after the second time I was forced to restart a level I just spent ages getting through (first because the darkness effect was making the game unplayable and you can't change settings mid-game, second 'cus I got stuck in a wall)
Nice for a trip down memory lane though at least, I remember playing the original version years ago back in the YYG sandbox days
