Nice job!  I played this to the end and had fun.  The mechanics worked well, and I thought you tuned the difficulty nicely so that it took several attempts to beat it, but each time I was making better progress and wanted to keep going.  I also liked how the lightning bugs had to be chased down when you get close to them.  I liked the darkening that happens at the end so that it makes it really difficult to make it to the lantern at the last second (this happened to me once, and I didn't make it).  (One apparent bug: I died my third death by a ghost once during that end fade-out, and I didn't get the end screen, it just froze until the timer ran the rest of the way down and the screen fully darkened -- seems like an easy one to fix).  Nice work!
