Thanks for playing! There was a last minute bug in the game jam build that prevent the game from recognizing that the 3 lightning bugs were at the heart. The post-jam build fixes that if you want to see more of the story.
Making everything large wouldn't have worked well for navigating around the forest. In early development, I had everything large, but it made moving around the forest way too tedious. Making things smaller lets your physical reach go much farther, and lets you get around much more easily. Also, in later parts of the game that were inaccessible to the game jam build, you need to be able to reach both hands out to be on the opposite sides of the blackout blights in order to shoot lightning between the deer and the lightning bugs.
I tried to get a zoom adjustment feature working but it was buggy and I couldn't figure out why, and had to remove it.
