I've managed to get all of the medals except the very last one. Even this much was enough to show how many ways this game can tell a story.
The best hero stories have more than one way to get the job done... especially if some of those choices have serious consequences later. That's this game, through and through. There are easier ways and harder ways, and you put the forked roads into the path before the player really had a handle on them. I might not have been too fond of the literal maze (impressive for a 2D toolbox, but the cave music got old kinda quick), but the overworld journey was well worth the trip.
Plus, I like games with increasing mobility, and it just makes sense to reward exploration with the power to explore more easily. Flying through the trees and scaling a mountain to outrace the clock -- good stuff.
Great job! (Thanks for the recommended games, too. So far, I've checked out the first and third of those.)
