The art drew me to this because it was so cute! The torch lighting SFX made me laugh out loud - I love it!
Overall, it was nice and I had fun. A few small critiques:
I would have liked to have some type of progress indicator. I got to around 19 gems and sort of just quit because I didn't know how much more I needed to collect, had no idea where I had not yet explored (Personally, I really wanted a minimap), and I was getting tired.
Also, the torch light dimmed a bit too fast compared to the light meter. You were essentially already blind long before the meter ran out.
