I enjoyed you game! It was short but good experience.
It was good that the game is simple to understand how to play, and easy to comprehend what's going on.
Although, I couldn't bring on what you did actually intend.
I tried to ignite a lantern like visual description but I couldn't, and tried to banish the fog(on the bridge) by liner magic but it didn't work. Also, I recommend to make the field brighter since to me it was hard to recognize field objects.
I'm looking forward to see the finished version!
