Megan Hunter's Worst Nightmare

I'm still trying to figure out the parallax backgrounds, which is tricky since I can't open VX anymore. But many of the town streets will look something like this, where you can only walk left or right using the giant sized boss sprites. Some screens are crossroads, so you can move up or down. Some of the actual dungeon maps are more traditional in being able to walk all around, but toon town and some dungeons feature this side to side look.
