I really enjoy this game. I played it once on Scratch, so I'm delighted to find it here as well.
It's short and simple to play, so it's easy to recommend to friends.
What gets me the most is the way its just black lines/shapes/drawings on a white background, but like, it's a CAVE to explore- with all kinds of different environments and decorations... The camera is fixed and the batteries are illuminated so you always vaguely have an objective of where you're trying to get to. It's very well designs and so very cool.
