I dig it!
Not sure how it matches with the theme, but it's definitely colorful (at least the walls are).
Only call-out I'll make is that it's very easy to exploit the bombs by triggering one, then 'surfing' the blast back onto any point of the maze. It makes it really easy to get to the exit.
Long term, it would be cool to see a version of this where the player could fall into a crater and not immediately lose (i.e. have to climb out or fall into a different maze). There's potential here!
