I cannot believe you completed this in a month. I assume you we're working from scratch, but its still truly impressive. The map has multiple areas, and the character controller is largely complete. It was very fun roll jumping, even thought i know it wasn't intended since it runs circles around most enemies.
This game feels so finished, most of anything that I could say revolves around the actual design, instead of technical issues or things that make the game unplayable. I could talk more, but I'd be echoing a lot of the other reviews here, and if this is the base you're working with, i think you have a good idea of where you're headed. Great work!
