Very nice game, specially for a first jam!
Really liked the art. The sword movement was nice, I could hit those weeds many times and it was satisfying. :P
The crumb trail is a good element to let you know where you have already explored (without using the obscuring of the sections), I noticed quite early that the cookies are not consumed if you walk over a place where crumbs exists,
The amount of cookies is more than enough to explore the whole labyrinth, which I think is intentional, but for me it meant I didn't not really have to make any decision of whether to explore a section or not, which can arguably be a good thing, depending on what you are going for.
Anyways, good stuff!
