This looks like a pretty interesting hack! I quite like when a hack can combine new graphics with the older/default ones. I LOVE the tall-grass tiles, and I also love the screen that shows you picking one of three eggs. I'm just caught up in the screens, they're all so cool XD
One small thing on the graphics front:



In this screen, at first I thought it had a few tile errors, but it's just the shading of the tiles- I think you should consider adding a darker outline to the platforms and bridges so that they stand out more from the rock/ground tiles. :)

The story is very original and looks quite promising, in my opinion. In general it looks like you've made a great start on this hack, and I can't wait to see more! Keep up the great work! :)
