Man, there is a lot of map here. I liked the rewind as an alternative to savepoints (though once I was trying to rewind "all of that jumping and then falling and then jumping and...", I kind of wished it would go faster). But...I made my way to the double jump ability, and then I made it back up to the starting point, and from there there was, like I said, so much map that it was hard to know where to go and which places would even lead anywhere.
